My husband has a 91 gmc 2500 sierra 2wd, the transmission went out the other day, it would not go into gear, We went to the junk yard and got a used 95 year 4L80E, but the yoke was not on the 95, is there repacement parts for yokes for a 95 and would a 95 replacement part fit a 91, Also If the vehicle doesn't go into gear what exactly is wrong? is it the torque converter, the filter,or the whole transmission?
No tail shaft interchange available. go back to original tranny and make sure you have a good electric connection in your wires. if you do put a new computer in your truck. i went through five new and rebuilt trannies and three reputable mechanics before oe finally found the trouble. he put a used computer in just to make sue it wasn't the computer. guess what? hope this helps you.
Drives good in thrid/overdrive.no reverese and 1st and second are shifting real high.changed 1,2 and 3,4 shift solinoeds and filter.1995 gmc 1 ton 3500 2 wheel drive.I think a band or something broke.I can drive it and has all the power it always had.
I have a 1996 gmc sierra 2x4, transmission works presently, its only shifts to 3 thousand rpm for the first gear then goes fine, shifts very slow also, i was told it could be the gear ratio, also when i do a lot of city driving stopping and going time to time the transmission will shift hard. if anyone can give me some tip of what it could be it would help a lot.mechanics are guessing..
