Poll: What is 'normal' overdrive behaviour?

[Pepsi90919]

My car (92 bonneville) has a very talkative transmission. It likes to talk mostly when hitting overdrive.

Now, it kicks in at about 63km/h. That depends on how fast you accelerate of course, but that's about average. I know that if you are to drive around that range, it's going to end up going VOOM VOOM VOOM VOOM because it's deciding on what gear to choose. That isn't a problem for me, I either slow down or speed up. Normally when it does go into overdrive, you will hear the engine RPM speed up a bit then it will go GRRRRRR (kind of a grinding noise) VOOM and there you are. When you give it a lot of more gas it will go VGRGRRRR and then come out of overdrive so you can accelerate. Is this really a problem? My driving habits never really bring out these effects much.

My mom on the other hand, insists that something is wrong, yadda yadda yadda. Anyone got any ideas?

I dunno. Maybe I should just tell her to stick with 'little D.'

Dunno for sure , sounds like the torque converter lock-up might be screwing up . Id say you need some work on it , depends on how bad it is and or how much you care about what it is doing . Im not real big with GM stuff so I don't know the tranny in that car enough to toss out a real good opinion . Sounds like the GRRR you are hearing is a slipping clutch pack , slipping leads to burned clutches which leads to that gear and or more not working anymore .
