i would like to flush my tranny's fluids and then refill it with fresh fluid. is that something that i can do myself (or perhaps with a buddy)? what's the proper procedure and what kind of tools/equipment do i need?

also, i have an 87 f150 with a 302 and a 4 speed automatic. how can i tell which automatic tranny i have? according to the hayne's guide, there are several 4speed automatic trannys that i could possibly have. if there is a way to find out, let me know. thanks.

 

1) loosen the tranny pan bolts just a little, then remove the bolts from one side allow the fluid to drain, then remove the rest of the bolts (careful, there's still fluid in the pan, remove the filter and let her drip for a while; replace the filter

2) remove the flexplate inspection cover (front of transmission directly in back of engine); turn engine until torque converter drain plug is exposed, remove and drain converter

3) remove transmission lines to radiator and use some compressed air or 'tranny flush' from TCI to force the fluid out of the lines and out of the radiator cooler

Button everything back up; add about 3-4 quarts to tranny; start engine and pour about another 10 quarts in as fast as possible (better check fluid level after about 8 quarts). Done

While you're there, though, add a nice finned aluminum tranny pan with a drain plug and consider putting in a temp gauge and an additional tranny cooler up by the radiator. Some folks are even adding tranny oil filter systems. Depends on how hard you drive and how long you want the tranny to last!

If the selector reads prnd21 then it is a C-6, if it reads prodd1 then it is a AOd. Ford added the EFod in '89. The Aode was added in 93. I think, anyways you have either a C-6or a AOd...
