My jeep was shifting real rough/sticking from 1st gear to second. I work at a bodyshop at a chevy dealer so I decided to bring it to the mechanic there.
He told me he found pieces of metal in the transmission fluid and that it had to be replaced. He says this was all caused by a valve that wouldn't let enough fluid in. So I bough a rebuilt transmission.
I got it back today and was disappointed. It now starts rough as hell, makes a krrrrr-krrrrrrrrrr-krrrrrrrrr noise more at high speeds and when I let go of the gas it also makes another noise.
Could this all be caused by something he did wrong? Don't really want to go and tell the guy he messed up because I know the guy.
I would take it back to the mechanic, give him a ride so that he can hear and feel exactly what's going on, and tell him respectfully that you think the transmission was either defective or improperly installed since you had no such noises before the new transmission.
If he insists that the noise was there before, then take the Jeep to a different shop and have them diagnose the noise and print you out a repair sheet stating what they think the noise is and about how much it will cost to repair it.
If the independent shop tells you it's a transmission problem, then this guy who did your tranny has most likely screwed up either in the rebuild or the install, and doesn't want to own up to it.
Keep us updated, if it turns out this guy is trying to screw you DO NOT let him get away with it!
