Hi,
I'm about to change the tranny fluid/filter in my Blazer, about how many quarts of fluid should i expect to be draining by removing the pan and filter? I want to have enough on hand when refilling. Also, does anyone know the proper torque on the pan bolts? Should I use any gasket stuff?

 

Pan torque is 97 in.lb. (actual range from the unit repair manual is 7-10lbft or 84-120inlb)

A pan drop will require about 5qts so if you had 6qts on hand you would be set. A dry transmission takes 11qts. It never hurts to have a few extra quarts of fluid on hand.

 

Thanks Kyle, How r u doin? I more thing with this pan removal the linkage on the side of the pan?

 

If the linkage has the mount using the pan bolts, just unbolt it and move it off to the side.

 

Kyle I cant even get a wrench in there with that cable, and is there a torque sequense for the pan? Thanks pal.

 

It is possible, believe me. IIRC, I had to use an open ended wrench on one of those bolts.

And no, no real sequence. I will get it all close by hand using a 1/4" ratchet.

 

Ok, 1 more thing should I use any gasket sealers, if I can't the pan spotless? I hate leaks !!! Remember I am a Fire Sprinkler Fitter !!!

 

NO
Do NOT use any gasket sealers.
There is a little hole that drains the tranny back into the pan, you will plug that hole and fry your tranny if you use the sealer.

best thing to do is cleant he mounting surfaces with brake cleaner. Put the new gasket between and button it up. The best torque sequence is to cross back and forth. Never work in a circle around the pan. I like to start at the 4 corners and work my way around, alternating corners, etc until done. then torque in the same pattern. It doesn't take much torque, too much torque and you push the gasket out of place, leading to a leak.

 

okay, thanks very much.
