Hi, I’m hoping to get some answers, my husband bought a 1991 chevy c1500 it has a 350 engine and the transmission is a 700r4. The guy said it shifted a little hard and said something about a vacuum line or something I may not be right on the exact wording but my husband found out whatever the guy said it was apparently either wasn’t the problem or it didn’t exactly have what he stated I don’t remember honestly but it shifts really hard from 1st to 2nd and will only shift smooth if you hit the gas hard like your just stomping on it. If your driving normal speeds and accelerating at a normal speed it acts like it doesn’t want to shift to second you can hear it the engine like whine a little then bam it will shift hard. Once your past that it’s not too bad. He’s replaced several little things that he thought could possibly fix the issue and nothing has worked. And the other day when coming home from work it won’t shift past 2nd, he only can go from 1st to 2nd. It will not shift to 3rd. What exactly does this mean? Does he need a new transmission or to have this one rebuilt? He’s pretty good at working on vehicles but he’s never really messed with transmissions so I don’t know how he would feel about rebuilding on his own if that would be hard or not, we just spent all this money getting him a truck and it’s a very nice truck, and realllly can’t afford to pay no 1k+ on getting a new trans. Not sure what to do in this situation and our local tranny shop has horrible reviews and they try to screw people out of money is the word around here. They also overprice like crazy. Would love some helpful advice... also I haven’t asked my husband but figured since this sounds like a place where I could find the info I need and it be reliable , can a different trans be put in? Like we have junk yards around and of course people selling different kinds of trannys so is there one that would work with his truck and engine that nothing would have to be altered? Or would he need the exact same kind of transmission? Just didn’t know if it would be easier to find one that could be for sale for 500$ or less that would work possibly? Thanks for taking the time to read and bare with me I know nothing about mechanics and all that lol but I can relay any questions or answers to my husband! Thank you!!!!
