Question about 1995 GMC Jimmy
95 GMC Jimmy. 4.3w engine, Mid size SUV. Has 1st and 3rd and reverse. Strong in these gears but no 2nd or OD. Replaced shift solenoids but same problem. Seems to lock up converter in D when on highway.
Have run this truck a year with only 1st and 3rd, towing everything imaginable without any problems except missing 2nd and OD. Changed fluid and filter also, Pane excaptionaly clean inside, but no change.

You might want to try this if its got a kick down cable unhook it from throutle body and pull it out as far as you can and let it snap back, do this a few of times, sometimes a valve gets hung up inside valve body of trans. and won't let it shift. If that don't help you may have to pull pan to dislodge it if thats the problem. chk. the plug on trans. (Its a 4 wire white plug) with test light with key on to see if there is power down there one will be hot, thats for overdrive, now on top of intake in front throutle body there is a sending unit that looks like a temp. sending unit with a 2 wire plug on it that sends a signial down to that plug when engine gets to temp. to let it shift to overdrive. Maybe this will help, or give you some ideas.

There isn't a cable on these! It is electronic. No 2nd or 4th means there is something wrong with the band.
