Hi everyone and thank you for reading my post. Any advice will be greatly appreciated. So my motor shot on me and my transmission was slipping between gears shortly after buying my crew cab. So I swapped motor, tranny, tcase out of a parts ZR2 I had. I also used the PCM. No tranny problems yet. The rod bearings soon gave me problems after a month of driving. I finally got a different motor out of a Silverado my wife wrecked. Ever since I've been driving it now, while I'm cruising down the highway the rpm's would jump up and down about 200 rpm and it seemed to be running higher rpm's than I remember going down the highway. And when I'm cruising at a low speed, sometimes the truck would rev high and tranny would seem to slip. Then the other day while driving around I heard a small grinding sort of sound, almost like two discs running together and that's when she just stopped pulling down the highway. I parked it, assuming transmission wss shot. When I go-to retrieve the truck I started it up and surprisingly it took off and I drove it home. Since then, I can start it and go through the gears, but it still runs high rpm's and it feels like something is holding it back. Then when I slow down and proceed to accelerate, it won't shift into 3rd and will eventually not pull anymore, like before. If I shut it off after I spew down it will run through the gears, until I slow down and shut it off. I'm clueless! If anyone knows something I don't I thank you in advance for any idea's.
