I have gone through the posting I decided to ask for help. I have a 1990 suburban 3/4 ton 4x4. I love this truck. this is a long story so please hang in there.
I bought this rig 10 years ago and the bb was out and replaced with a 350. I drove the hell out of it for 6 years. All of a sudden the flex plate started rubbing the dust cover on the bell housing. That was a easy fix....Just took off cover. A month later it developed a bottom end knock. So the decision was made to take a old 400 and build it for towing. !yr and 6k later we had a rebuilt motor from a reputable shop. we installed it and added a sniper kit. it was running great. Did the 500 mile break-in and in the last 25 miles i heard a familiar sound. yup Flexplate again and it had 1/2 in play in crank.
Builder said " ballooning trans did it" . Angry with myself now, I asked him to fix the motor and asked who to take the tranny to.
Now i have a newly rebuilt motor, t400 , transfer case, and torque converter.
Drive 400 miles and decided to give it a check up.
thrust bearings have to much play again. i cussed ,cried, asked god why, and threw myself on the ground for a fit. then sent trans to a different shop to get my rebuild checked 200 bucks. checked all the lines and cleaned them out each time. New cooler. I dont know what else to do. So frustrating and I am about 10k in.
