1991 Chev. 2500 Tranny slipping?
Durring normal freeway driving at 55-65 the engine speed is normal durring acceleration. Soon after I reach cruising speed, the engine speed increases. If I push slightly on the gas pedal the engine speed decreases and I can feel the tranny "lock in".
Also, if while cruising, I take my foot slightly off gas pedal it tends to "lock in".
Trans fluid fairly clean. Not burned.
The transmission works wonderfuly all other times.
What gives? I don't want to waste a bunch of money on the wrong repair.

It never hurts to have the transmission fluid changed.
Once I had an AAMCO transmission shop tell me that my tranny was going out on my Trans Am because it wouldn't shift. After they had dropped the pan and changed the fluid it worked fine. They looked pretty stupid trying to cheat me like that. I'm not a transmission expert but at least you won't be wasting money as it's a good maintenance thing anyway.
feels like your a lead foot youthful driving force to me.14 rushing tickets(one million-14 over) could be 28points right here in michigan (something above 15 over shrink is a court docket case right here).12points being the shrink to be allowed to force.You had maximum suitable sell the motor vehicle and use the money to purchase some thing slower and greater secure.i think of you're able to finally end up driving a bus .persevering with on a path with that automobile you're able to positioned your existence in grave risk(voice of journey I crashed a automobile drag racing at 115mph on an area hwy lower back whilst i exchange right into a teenager new approved driving force i exchange into very just about killed I blew a tire and rolled it). additionally in case your caprice has a 350 it must be a vett engine maximum caprices with a v-8 have been 305 engines(I owned one)the 350's have been put in the police or detectives autos yet no longer with quicker's.i do no longer understand if it exchange into obtainable as an orderable engine whilst new to the prevalent public however the police did have them .yet maximum caprices with a V-8 that i understand of have been in basic terms 305's in any different case.
Two suggestions. Number one, put a quart of Lucas tranny treatment in with your tranny fluid. Try that for a couple of days. That stuff can work miracles!!! If that doesnt work, take it to a tranny shop, call around to find one that will look at it for free. A good idea would to ask around for a trustworthy tranny shop while you are at the parts store buying the Lucas. Good luck.
Sounds like maybe a belt might be slightly slipping. I would first try some lucas tranmission hunny and see what the does for you. It fairly cheep around 10 to 12 bucks depending on where you get it.
When is the last time you had the trans serviced? Good chance the filter is plugged and cannot get enough fluid through.
You need to have that thing hooked up to a diagnostic computer [or whatever you wish to call it] because your shifting would be almost completely electronic.
its the torque converter, a hundred some dollar part
4L80 trans sucks
