Tranmission noise?
When the engine/trans is warmed up, most noticeable while starting from stops under normal throttle, there is a whine/buzz sound. I first thought it were the valve-train but, the sound is not there while the engine is revved up without moving.
History of the car, has a cam, tsp springs, p/r, CHE, Circle D 3200 and all the other supporting mods. The sound is noticeable and hopefully it can be heard on the videos if you listen for a whine type of sound. It happens with ac on or off and does not appear to be from the front of the engine and again only happens while accelerating. While the engine/trans is cool I do not hear the noise at all. In drive when the engine is warm there is a small "whirl" type of sound when stopped at a light, not loud but if I put it into neutral the sound goes away. A video cannot capture that sound as it is very low. The main sound I am concerned about is the buzz/whine sounds under acceleration. In the first video you can hear it at the 3 second mark to have a good reference of the sound. Second video some good sounds of it around the 5 second mark. Thoughts? |

Turns out it was the TC but they also found the clutch drum had cracks which may or may not have caused the noise. Not sure since the drum was replaced with the TC.

Was gonna say that. When the Precision 3200 TC in mine decided to crack the hub where it goes into the trans front and engage toe pump, it expanded and I heard these same kind of noises, plus trans fluid under my Camaro and by the time I got her to the shop it had wiped out my front pump housing and all the seals and the pump. The TC was still under warranty but the rest of the damage was about 1500 bucks!! Ouch.. Glad you found it before all that..

I had an ADM transcooler on it prior but was bypassing the radiator. I had them rehook it back to the radiator, but it looks like they got the routing wrong. Now it goes to the cooler first and then to the radiator. Not sure how big of a deal that is but I thought it should go to the radiator first and then the cooler. My cost for all that parts/labor was about $2,900 :( |
