When shifts into OD hear/feel a shudder or clunk, 95 PA

My 95 PA transmission makes a racket and you can feel it kinda shudder when the trans. changes into Overdrive. Not really a clunking racket but more of a shudder, hard to describe. When it shifts into overdive is the only time I have noticed it.
Thanks for any help or tips.

This can be caused by a misfire , slipping TCC and/or bad tps, this requires a full scan with a high line scanner that can pick up trans functions also.

I am pretty sure it is not a misfire but not positive...

What is the TCC? Torque Converter?

It does it on the upshift as well as the downshift.
Sounds like the torque converter?

I will get it scanned and see what the results are.
The car only has 72,000 miles on it. I was thinking of replacing the filter in the trans and changing the trans. fluid and perhaps adding some Lucas trans additive but I doubt it will help. I also dont know if the trans has ever been serviced...
Thanks for the help.
Any more tips appreciated.

Hiya,
Atorque converter is often described as going over rumble strips during the shift. Hope this helps. TT

You nailed it, that describes it perfectly.

So does the Torqueconverter just need replacing or is it more serious than that. Reckon how long it will last if I just drive it and dont replace/repair it?

Thanks

Thanks for the replys so far.
I would like to gather more information on this problem, I tried searching the archives here but have not really been able to narrow down the search enough to help, so far.

Can any of you folks provide a link to more info, or explain further?
Is this an electrical problem such as a switch or is it a mechanical problem?
Will the Torque Converter need replaced?
Or do I simply need to have the vehicle scanned to determine the problem?

Thanks for any tips or help.

See my post!

H,

Sorry for the delay. I'm not sure how that failure plays out. I was under warranty so I had mine replaced. Good Luck.
Also, you could just replace the converter but I know a new one can list for lots.

I put some of this

in it and it seems to have solved the problem, for now anyhow.

Thanks for all the replies.
