76 318 Duster, 998 trans?

D32 trans code (hamtramck doesn't show anything for that code on a '76 Duster)....

Problems: Hard clunky shift into reverse (resulting in entire car shaking, and also will often kill it if the brakes are locked or the p-brake is on) with other gears being stiff, but not what I'd consider a hard shift; Whine in 1st; no power, fairly sloppy when applying power, etc; Can stand on the brakes for days and not bust the tires loose. Could be the result of a very tired engine, but I'm thinking if I helped the trans out a bit, it would probably thank me for it...

First things first, I wanted to drop the pan and try a flush, or at the very least get some fresh ATF in it... Anybody know the capacity of the 998 (or whatever the hell D32 code is) for ATF?

Also, what should I look at for pumpkin goop? I was thinking I might want to put new diff oil in, but not sure how much to get or what is recommended for a hot climate such as El Paso in the summertime... Suggestions?


Thanks,
