I thought I'd start a follow-up to another thread that I jumped into: Start/Trans issues
I recently purchased my 88 B2 EB from another member here w/ some knocking come from the automatic transmission. It ran through the gears fine and drove fine. The knocking sound was coming from the trans. The trans had been rebuilt by AAMCO about 30k miles ago. Inspection showed the passenger side lower trans/bell-housing bolt was completely gone and the middle one (same side) was backed all the way out and about to fall out. I replaced the missing bolt, tightened the other and the rest checked okay. I removed the starter and examined the flex plate but did not see any noticeable cracks.
After re-securing the trans, the knocking was still there as well as a new leaky rear-main seal (yay). I am fairly mechanically inclined and have done some serious projects (diesel swapped a CJ8 and back), but I don't really like messing w/ automatic transmissions. So I took it to a local transmission shop to have it looked at. Their initial diagnosis:
1. Bent flex plate with cracks
2. Rear main likely caused by trans being loose and then re-secure.
3. Unknown additional until they get it pulled.
Initial quote of about $1100. Still waiting for the final bill but I told them to just make it right. I've done rear-mains multiple times on my Jeep and I really don't want to do another!
I will keep you posted. In the mean-time, I'm working on a new-to-me rear hatch that has the removable glass and a working locking mechanism.
