My 1991 940 just started vibrating this morning, even when increasing rpm in park or neutral. I had a tranmission rebuild 2 years ago, and 1 year ago had problem with delayed and eventually lost reverse. That was fixed, but when idling seemed like had a odd worbbling sound (I know what is that? Hard to explain). When the tranny was rebuilt they had a new torque converter built for it.
Does this all add up to a bad torque converter? When driving, the vibration become more pronounced when letting off gas. I'm going to get under the car and look at the drive shaft, but was recently under it and did not see any issues, so not expecting that to be the problem.
Thinking should have gone for the junk yard replacement instead of $1500.00 rebuild.
Thanks,
Gary
