ok,

a buddy of mine's car is acting up and I'm woundering if it's the tranny or flex plate... if he drives normal, his car drives and shifts fine... (it shifts very firm) But if he gets on it, no matter what gear he is in, the car will drive almost like a manual with the clutch going out drives... the engine revs quickly, but the car doesn't really accelerate (my blazer picks up speed faster than his car is at WOT) It has been doing this for about a week or so now and just continually getting worse. I'm thinking that it's the flex plate, but a gentleman over at Tuffy stated taht if the flexplate is going out, it would be making clanking noises or something. What do you guys think?

oh, he had the fluid changed today.

 

The flexplate is nothing more than a piece of metal connecting the torque converter to the crankshaft. It pretty much either works or it doesn't, not much in between. That is why they said it would likely be making some horrible noises if it was bad/broken. Could be many things internal or otherwise but not likely the flaxplate.

 

the only other thing I can think of is maybe the tq converter...

as far as internal, I don't think so considering as long as it doesn't go WOT, it's fine and shifts firm...

I am not even close to knowing much about auto tranny's.
