The converter in my '65 Polara used to make a noise when taking off from a stop (I coverted to a 4-spd, so it can't make the nosie anymore). To me it sounded sort of like a jet engine starting, so I had no complaints about it. I'm pretty sure it only made the noise as the converter was hooking up, and not continuously. Anyway, never posed a problem.

concerned about my new 64 cudas 904 torqueflite. it supposedly has a shift kit in it. but the torque convertor is stock. the first thing it does is a gentle hum it makes when u take off, its not a violent or rough sound but i have never heard it in an automatic tranny car before. i beleive it stays there but just gets obliterated by road noise as the speed accelerates. Do shift kits make trannies sound deffierent. Then the second concern is a slight rev between 2and 3 . U can see it rev about 200-300 rpms between shifts on the tach. can that be adjusted out?? thanks neal zimmerman, eugene oregon
