Product Details

PLEASE NOTE: Cal. 1985 models with 722.416 use a different pan gasket! Check you transmission number before ordering.

Comes with Kent's general transmission service tips and tricks video. He recommends doing a power drain to get all the fluid out. See the kit below and click on it to learn more. If you would just like to purchase the gasket please see related products for availability. Consider replacing your old pan to avoid leaks. See related products below.

What fluid? We get lots of emails asking about where to get the correct fluid. We do not sell the ATF because of the high cost of shipping.  It is available in many auto parts stores but you MUST ask for Dexron III. I do not recommend full synthetic as it can leak by your old seals.

Here is what you can get at AutoZone.

1981 to 1995 722.3 722.4 722.5 New Transmission Pan Replacement w/ Magnets

Fits many models during that period. See complete list below. Late W123, Late R107, W126, W201, W124, R129 and W140

These transmission pans get "out of shape" due to over-torquing the bolts. That crushes the stops (see below), and when that happens, it is very hard to get the pan seal not to leak. Your best option if you are doing a transmission service is to replace the pan.
