So guys, I've been hunting for used transmission pan for a while now with now success. I have gave up and I am going to buy my pan from 928international. But there's 2 pans under 4spd but both have different serial numbers.

Number: 960-307-031-04

2nd: 722-270-091-2

The Forgotten On

The 722 part number is the Mercedes part number and the 960 is the Porsche part number.

I see, so there no difference in terms of fitting the actual part on to the tranny?

Hollisterkiid92

so another question, would a manual transmission pan fit a automatic transmission pan??

No. Completely different.


Call Tom and get exactly the parts you need. Remeber the correct filter, sump gasket, and the two drain plug seals. On mine, I've decided that replacing the seal between the reservoir and the tube on the pan is a good idea at the same time.

If you don't have an inch/lb torque wrench for the sump bolts, now's a great time to invest in one. The list of Most Common causes of pan leaks is topped with "improper torque used on sump bolts", then goes on to other fluid change related oversights, then to "old-style gasket used", before it gets to hose and o-ring failures.

ALSO make sure you get the REVISED MB pan gasket to avoid leaks. The old one tends to split near a centre bolt. check with an MB dealer.

Man trans rarely have pans. I was once charged for a 'transmission service kit' by a dealer....on a 5 speed manual car.

Trying revive this post, I recently bought the pan with the serial that starts with 960, so would it fit if my tranny is stamped with a serial that starts with 722???

Did you see this a few posts up the thread?

Hollisterkiid92

I did, so they are the same pan just different serial numbers then? Just want to be clear on it.

Mrmerlin

yes the pan will fit perfectly,

NOTE make sure you correctly position the tank O ring in the groove then carefully screw down the collar.

NOTE also is a good time to RnR the bowden cable housing O ring, since the pan is off,
it makes easy work of reattaching the bowden cable.

Thanks bud, saved me from having to return my pan:-D I'll definitely check the Bowden cable as well.

I replaced the O-ring on the Bowden cable fitting (leaking). If you pull the yellow fitting and do NOT see the old O-ring...it's probably slipped down the lever arm mechanism to the horizontal arm attached to it. That's where I found the old O-ring on mine - after dropping the pan during a trans filter and gasket replacement job. I've read a few posts by folks who reported not finding the old O-ring. Good bet they all slipped down.

You may want to look for a torque driver rather than a wrench. Everyone sort of use the term "wrench" when talking about torque tools, but what you need is a tool that torques to less than 10 in/lbs (5.9 to be precise). Most wrenches I've found don't go lower than 20 in/lbs, so be careful what you order because they're usually pretty expensive.

Right numbers...wrong units: Manual states: 8 Nm on the ATF pan bolts. 8 N-m = 5.9 lbs-ft = 70.8 lbs-in.

Yesterday I picked up a 20-200 in-lbs (lbs-in) torque wrench for $15 at Harbor Freight. It certainly isn't the best, but other than trans or oil pan bolts I can't think of when I'll use it again. The main purpose of the tool to my mind is to prevent me from significantly over tightening the bolts - which is so easy to do because the torque specs feel impossibly low to anyone without experience replacing these pan gaskets.

Thanks very much for correcting that, it was late and I should have said "IIRC", which I didn't. I remembered 5.9 in./lbs. because its stuck in my mind that the torque on those bolts is unusually light.

BTW, my WSM just happens to say 7nm, 5ft/lbs. (Printed in Germany - VI, 1982 Replacing ATF and Filter 38-27). No idea why it's different from yours, or why I remembered 5.9. Why would I remember a number that's in your manual and not mine?
