when you remove and clean up the old pan put the edge on a flat plate and tap down the bolt holes. they get bent up from too much tightening and need to be brought back to level.
it has been recommended here to use Mobile 1.

Back to tranny fluid...
I'm a firm believer in Amzoil. I have it in my 97 Dodge caravan and I have 211,000 miles on it and it's still going strong. And I'm not nice to it either.
I use amzoil in my engines too, they stay clean and tight.

I personally like using a dry gasket in this application. The premium ones are "self sealing" meaning that they swell up around the pan screws and between the pan and the mounting surface of the transmission. The gasket is available in a kit which includes the filter. If you use a self sealing gasket, make sure the pan is straight around the mounting holes, and do not over-tighten the screws, you should not have any problems with leaks. Using RTV will make for a lot more clean-up next time you have to change the fluid. JWID

I didn't realize that Caspro had an aluminum pan. i just went to their site and see the picture of it. It looks just like a Ragusa aluminum pan. I wonder if they are just reselling Ragusas.
Anyway, I am using the NAPA fiber gasket with my Ragusa pan and it works well.

Mine was put on by the PO and has been on a long time. I have the Caspro instruction sheet. Is it a resell of Ragusa or a Ragusa copy of a Caspro? I don't know and, to me, it doesn't make any difference. What I know is I can drain the ATF without ending up wearing a quart of it.
Thanks for the info on the pan gasket.

I have a recollection that someone knowledgeable recommended not running synthetic ATF unless the trans had been newly or recently rebuilt. I believe it was because the synth ATF could loosen up some crud and cause problems. If pressed to say who I would say Manny as that is one of the few I would accept such a comment from. The reason could also be there was not enough benefit from the synthetic in an old trans.
Does anyone have a better recall or better information on synthetic use in an older trans?

I got 120K out of my Lebaron's tranny...
... It was a manual, however, and still going strong when I sold the car.
It was a V6 convertible and I was not nice to it, never changed the oil, and never the gear oil. New Process tranny was pretty stout.
I have Coast ATF in my GMC. It is what Manny used.

Lets get back to the original subject.
Bob Drews recommends and uses John Deere Hy-Gard Hydraulic/
Transmission Oil in his transmissions. It is the same formulation
that many racing transmission shops sell as High dollar fluid.
