I have a 2000 offroad 4x4 extendacab with the 46re tranny and i dont know to much about the tranny but i hear you guys talk about changing to the atf-3 and atf-4 fluids and then adjust the belts.......ok how do you do this and why would you do this????Is the atf-3and4 the best to put in it or not????

 

i TRIED TO FIND THOSE POST FROM BEFORE BUT I CANT FIND THEM!!!!!!

 

Don't forget to grease the muffler bearings............just kidding. They talk about adjusting the bands, not the belts. As far as the atf fluid, I would stick with what your owners manual states.

 

Atf+3 or +4 will be fine for your transmission. As far as adjusting the bands...there's two bands, one is external and one is internal. If I remember correctly, both get torqued to 75 in.lbs., then backed off two turns, but check a service manual to be sure (I'm sure someone else will post and correct my memory too ).
