I have a loud whirring noise, and its constant, regardless of whether the transmission is in Park, reverse, neutral, drive, etc. Doesn't matter. It is always there as soon as I start it up. However, the car shifts fine - which is perplexing.
For those of you that didn't already know, I just finished a deep and prolonged engine refresh (I left the rotating assembly alone as it only has 80K miles), bolted the transmission up to it and put it back in the car after working on it for the past year...
Initially I thought it was the starter drive (bendix) hanging onto the flexplate ring gear was causing the whirring noise, but when I probe into the transmission bell housing with my borescope, I don't detect any problems with the starter drive. Now, it is possible the starter drive is releasing once I shut off the car and may be hanging only while the engine is running, but I have no way to verify this.
I talked to a transmission professional this morning. When I initially removed the drive train, I took the transmission to him and they replaced the front and rear seals and took the front pump apart and replaced the bushing. This is all they did and I feel reasonably confident they didn't mess anything thing up.
I was the one that reseated the torque converter onto the transmission. It was a little difficult to get on because of the new bushing, but it went on and I verified (took measurements) that the torque converter was seated onto the input shaft correctly. I also verified I could rotate the torque converter AFTER we had mated the transmission to the engine, prior to bolting the torque converter to the flexplate.
I am going to take the car to the transmission shop next week and let them try to diagnose the noise but I have a have a nagging feeling that I am going to have to remove the transmission at some point. IF I have to do it, I want to know if it is reasonably possible to remove the transmission from the vehicle - as I have no desire to pull both the engine and transmission as a unit again.
The exhaust is a piece of cake, so I am not worried about that. Getting the starter out will take some work, but with the exhaust out of the way, it shouldn't be too bad. I am more concerned about getting to the top bolts of the transmission while the engine is still in the car. Am I going to have to tilt the engine to get to the top transmission bolts? And how hard is it to mate it back up to the engine? Am I going to be cussing both on the removal and the installation?
Sucks to be me right now. Spent a year putting this thing back together, not to mention the parts cost I have invested in this and I'm feeling no joy because of this incessant whirring noise.
This is not my daily driver, so there is no rush to get this fixed. The car is in my 2nd garage and I have a lift in the garage, so I am well equipped from that perspective, but I may have to step back from this problem for a few days/weeks before I feel the desire to go work on it.

Might Have to Possibly Remove the Transmission - Anybody Been Down this Rabbit Hole?
