Ford C6 Transmission Pan Gasket — Moroso 93108 Compatible

Compatible With the Moroso 93108 Application

This aftermarket gasket is marketed as compatible with:

Moroso 93108

Moroso’s genuine 93108 is the company’s Perm-Align Ford C6 Transmission Pan Gasket.

Moroso officially specifies genuine 93108 for:

Ford C6

and:

Moroso 42060 Ford C6 Transmission Pan

This replacement should therefore be described as:

Moroso 93108 Compatible

rather than represented as a genuine Moroso gasket.

Genuine Moroso 93108 Specifications

For comparison, Moroso manufactures its genuine 93108 from:

40-durometer rubber vulcanized to a rigid steel frame

Moroso specifies:

Thickness: 3/16 inch

Quantity: One per package

Sealant: Not required

Moroso says its reinforced rubber-and-steel construction is designed to outlast conventional cork-composite transmission gaskets while making repeated transmission-pan removal easier.

Those specifications apply to genuine Moroso 93108.

They should not automatically be applied to this aftermarket replacement.

Aftermarket Gasket Construction

According to the supplied manufacturer information, this replacement uses:

0.8 mm galvanized cold-rolled steel reinforcement

combined with:

70-durometer oil-resistant rubber

The finished gasket is specified at:

3/16 inch thick

Those are useful specifications, but they should remain attributed to this aftermarket manufacturer.

Do not describe them as Moroso specifications.

In fact, the distinction matters because Moroso specifies 40-durometer material for genuine 93108, while this aftermarket listing claims 70 durometer.

Why the Steel Core Matters

A steel-reinforced gasket has several practical advantages during transmission service.

The internal reinforcement helps prevent the gasket from:

• Folding
• Stretching
• Sagging
• Shifting around bolt holes
• Moving while the pan is positioned

That’s especially useful when installing a transmission pan from underneath the vehicle.

Instead of trying to hold the pan, gasket and hardware simultaneously, the rigid gasket maintains its basic shape while the bolts are started.

Full 3/16-Inch Thickness

The gasket is specified at:

3/16 inch thick

This is also the thickness Moroso publishes for genuine 93108.

The reinforced construction provides substantial sealing material while the steel frame controls the gasket’s shape.

The objective is consistent compression around the entire pan rail.

But a thick gasket still can’t compensate for a badly damaged transmission pan.

Designed for Flat Mating Surfaces

This is one of the most important installation requirements.

The supplied manufacturer information specifically states that this gasket is intended for:

Smooth, flat mating surfaces

and should not be used on pans with incompatible raised sealing surfaces.

Moroso makes a similar distinction with genuine Perm-Align gaskets.

Moroso’s current installation instructions state:

Perm-Align transmission pan gaskets are recommended only for flat-rail cast-aluminum or billet-rail transmission pans.

That makes pan design an important part of fitment.

Ideal Match for a Billet-Rail Transmission Pan

A rigid gasket works particularly well against a:

• Billet pan rail
• CNC-machined rail
• Flat cast-aluminum rail
• Properly machined sealing surface

These surfaces resist the deformation that commonly affects thin stamped-steel transmission pans.

That’s exactly the type of sealing interface Moroso uses with its own Ford C6 pan.

Moroso 42060 Ford C6 Transmission Pan

The natural Moroso companion to genuine 93108 is:

Moroso 42060 Ford C6 Transmission Pan

Moroso manufactures the 42060 from fabricated aluminum with a:

One-piece billet rail

The rail is:

CNC-machined after welding

to improve flatness and fitment.

Moroso specifies the pan at:

2.000 inches deep

and includes:

• Magnetic -8AN drain plug
• 1/4-inch NPT port
• Serrated flange hex bolts

Moroso specifically pairs:

42060 Pan → 93108 Perm-Align Gasket

That makes the 42060 an excellent ecommerce cross-sell for C6 customers upgrading the entire transmission-pan assembly.

Why C6 Transmission Pans Leak

A leaking C6 pan doesn’t automatically mean the gasket failed.

Common causes include:

• Distorted pan rail
• Raised bolt holes
• Uneven bolt torque
• Overtightened bolts
• Old gasket material
• Dirty mating surfaces
• Excessive sealant
• Incorrect gasket
• Damaged transmission case
• Fluid leaking from another component

Before replacing the gasket, clean the transmission and identify where fresh fluid first appears.

ATF has an impressive ability to travel along a transmission case and frame the pan gasket for a leak it didn’t commit.

Check Above the Pan

Before removing the transmission pan, inspect other possible leak sources.

Depending on the C6 installation, transmission fluid can potentially originate around:

• Dipstick/filler tube
• Shift-selector shaft
• Cooler-line fittings
• Servo area
• Front pump
• Tailhousing/output seal
• Vent
• Case fittings

Clean the transmission first.

Then locate the highest point where fresh ATF appears.

That can prevent unnecessary pan removal.

Inspect the Pan Rail

Once the pan is removed, inspect the sealing rail carefully.

Look for:

• Distortion
• Raised bolt holes
• Cracks
• Burrs
• Gouges
• Corrosion
• Old gasket material
• RTV residue

A straightedge can help identify distortion.

A reinforced gasket performs best when both mating surfaces are genuinely flat.

Raised Bolt Holes Cause Leaks

Stamped transmission pans can become distorted when their bolts are repeatedly overtightened.

The metal surrounding each bolt hole gets pulled upward toward the transmission case.

The result is an uneven rail.

When the pan is reinstalled, the gasket becomes heavily compressed at each bolt but receives insufficient compression between the fasteners.

That can cause another leak even with a brand-new gasket.

Correct minor distortion appropriately or replace a badly damaged pan.

Clean Both Mating Surfaces

Before installing the gasket, remove:

• Old gasket material
• RTV
• Dirt
• Oil residue
• Corrosion
• Burrs

Avoid damaging the transmission-case sealing surface while cleaning it.

The finished surfaces should be clean, dry and flat unless the actual gasket manufacturer specifies otherwise.

No Sealant With Genuine Moroso 93108

Moroso explicitly states that genuine 93108:

Requires no sealant.

Moroso also warns against using sealer with its C6 transmission pan because pieces of sealant can break loose and potentially obstruct transmission or transbrake passages.

This aftermarket listing likewise says the gasket can be installed without sealant.

Follow the instructions supplied with the actual gasket.

Don’t automatically coat a reinforced gasket with RTV.

More silicone doesn’t automatically create a better seal.

Sometimes it just creates silicone inside the transmission.

Install Every Bolt Before Tightening

With the gasket and pan properly positioned, start all transmission-pan fasteners a few threads by hand.

This confirms:

• Correct gasket alignment
• Correct pan alignment
• Proper bolt-hole positioning
• Thread engagement

Do not fully tighten one side of the pan while the other side remains loose.

The objective is uniform compression.

Moroso’s Current Perm-Align Torque Procedure

For genuine Moroso Perm-Align transmission gaskets, Moroso currently specifies a progressive tightening procedure.

After positioning the gasket and starting all fasteners:

First pass: Hand-tight to mildly compress the gasket

Second pass: 60 in-lb

Third pass: 120 in-lb

Then:

Repeat the 120 in-lb sequence

to confirm even torque.

120 in-lb = 10 ft-lb

Moroso provides a dedicated tightening sequence for 93108 in its current instructions.

If the manufacturer of this aftermarket gasket specifies another procedure, follow the instructions supplied with the actual product.

Moroso 42060 Torque Specification

Moroso’s installation instructions for the 42060 Ford C6 transmission pan specify:

10 ft-lb

for the supplied pan bolts.

That equals:

120 in-lb

which corresponds with the final torque in Moroso’s current Perm-Align procedure.

Again, that’s the specification for Moroso’s 42060/93108 combination.

Verify requirements when using another pan.

Don’t Overtighten the Bolts

Overtightening a transmission pan can:

• Distort the rail
• Crush the gasket
• Damage case threads
• Create uneven compression
• Cause future leaks

If the gasket is leaking, applying substantially more torque isn’t automatically the solution.

Find the reason it isn’t sealing.

Service the Transmission Filter

Pan removal provides access to the C6 transmission filter.

Moroso currently recommends the following filter for its 42060 pan:

Ford D3TZ-7A098-B

Moroso’s current 42060 product page also references a compatible Fram filter.

Always verify the filter for the actual transmission and pan configuration.

Servicing the filter while the pan is already removed saves repeating the same work later.

Inspect the Old Fluid

Pay attention to the fluid that comes out of the transmission.

Look for:

• Burnt odor
• Dark coloration
• Metallic contamination
• Friction material
• Water contamination
• Excessive sludge

Fluid condition can provide useful information about internal transmission health.

A new gasket fixes an external leak.

It doesn’t repair worn clutches or internal transmission damage.

Inspect the Bottom of the Pan

The transmission pan itself is a diagnostic tool.

Inspect it for:

• Metal fragments
• Friction material
• Excessive sludge
• Unusual debris

A small amount of fine material may accumulate over a long service interval.

Large pieces deserve further investigation.

Clean the pan thoroughly before reassembly.

Clean the Magnet

If the pan contains a magnet, remove accumulated ferrous material and inspect it.

A heavily loaded magnet can indicate internal wear.

Clean and reinstall it correctly.

If the pan does not have a suitable magnet and its design permits one, a magnetic drain plug can provide another way to collect ferrous material.

Moroso 97006 Magnetic Drain Plug

Moroso lists:

97006

as the replacement magnetic drain plug for the 42060 C6 transmission pan.

The plug is:

3/4″-16

and provides another logical ecommerce cross-sell for customers servicing Moroso transmission pans.

Reusable Gasket Design

The supplied manufacturer describes this aftermarket gasket as:

Reusable

Steel reinforcement can make repeated removal and installation practical when the gasket remains undamaged.

Before reusing it, inspect for:

• Cuts
• Tears
• Hardened rubber
• Permanent deformation
• Separation from the steel core
• Damaged bolt holes
• Chemical deterioration

Reusable does not mean indestructible.

If the sealing surface has deteriorated, replace it.

Why Reusability Matters on Performance C6 Builds

Performance transmissions may have their pans removed more frequently for:

• Fluid inspection
• Filter changes
• Valve-body service
• Transbrake service
• Transmission tuning
• Race-season inspection
• Internal modifications

A reusable reinforced gasket can make those service intervals considerably easier.

That’s particularly useful on a drag or street/strip C6 where inspection may occur more frequently than on an ordinary production transmission.

Transmission Temperature Still Matters

A leak-free pan doesn’t protect a transmission from excessive fluid temperature.

Performance C6 applications can generate significant heat, especially with:

• High-stall converters
• Heavy vehicles
• High engine torque
• Street/strip operation
• Towing
• Repeated drag-strip passes

An appropriately sized external transmission cooler can help control ATF temperature.

Moroso offers dedicated transmission cooler and filter assemblies that can be cross-linked from this product category.

Refill With the Correct Fluid

After reinstalling the pan, refill the transmission according to the transmission builder’s recommendations.

Do not automatically pour back the same volume that was drained.

Total required fluid depends on:

• Transmission pan
• Torque converter
• Cooler
• Cooler lines
• Whether the converter was drained
• Transmission modifications

Bring the fluid to the correct level using the appropriate checking procedure.

Inspect for Leaks After Installation

After servicing the transmission:

1. Refill appropriately.
2. Start the engine.
3. Follow the correct gear-cycling procedure.
4. Bring the transmission to the required checking condition.
5. Verify fluid level.
6. Inspect the complete pan rail.
7. Inspect cooler lines and fittings.
8. Inspect the drain plug.
9. Check again after the first drive.

A clean transmission makes new leaks much easier to identify.

Important Aftermarket-vs.-Moroso Clarification

The supplied listing includes these claims:

0.8 mm galvanized cold-rolled steel core

70-durometer oil-resistant rubber

Reusable construction

Those specifications should remain attributed to the aftermarket manufacturer.

They are not the published specifications for genuine Moroso 93108.

Moroso specifies its genuine gasket as:

40-durometer rubber vulcanized to a rigid steel frame

Both are 3/16-inch-thick reinforced gasket designs, but they should not be presented as identical products.

• The manufacturer specifies a different gasket design

Verify the actual transmission and pan before ordering.

Final Verdict

This Ford C6 steel-reinforced transmission-pan gasket offers a durable 3/16-inch-thick alternative to conventional cork and unsupported rubber gaskets and is designed for the same basic application as Moroso 93108.

The rigid internal structure makes installation easier by keeping the gasket and bolt holes aligned while providing controlled compression against smooth, flat mating surfaces.

For best results, inspect the pan for distortion, clean both sealing surfaces thoroughly, start every bolt by hand and tighten progressively according to the actual gasket and pan manufacturer’s instructions.

And if the C6 is still leaking after you’ve replaced the gasket twice, clean the case and look above the pan.

The laws of gravity have blamed a lot of innocent transmission gaskets.
