I do not usually ask for help on this forum. This is due to the fact that I have had 230k trouble free miles (mostly).

I just performed a major engine tune-up and overhaul. Engine runs great, my problem is that now the transmission “clunks” into first and sometimes when shifting from first to second. At the same time I tuned the engine, I changed the transmission fluid (Castrol ATF). I did not change the filter due to a lack of motivation.

I do not know much about an automatic transmission. Normally I would search the site for previous discussion (I hate to turn the same dirt for those of you who are regulars), but are there any suggestions for reducing or eliminating the clunk without pulling the engine and transmission for a transmission overhaul?

Regards,

Glen

 

Did you find out what the clunk was? I just noticed a clunk on the 1 - 2 shift when I was flooring the gas. I just had the VB Mod done 2 weeks ago. The 2 -3 and 3 - 4 are quick and clean under hard acceleration.
Is that clunk a bad thing?
Thanks

Any takers on the clunk issue?

has teh tranny ever been rebuilt in those 230K miles ? if not then it sounds like the beginning stages of the clutches starting to go in the tranny.

 

If that tranny hasn't been rebuilt for 230k miles, I think you deserve some sort of recogntion.

 

You didn't add the additive did you?
(dam that's the 3rd one today)

 

Turns out it was a broken motor mount. I also have a 280Z and jumped over to one of the forums that I keep up with and asked the same question there. One of those guys suggested the mount.

Car runs great now except for an exhaust leak where the manafold bolts to the head (major pain to fix).

Thanks anyway. Hope this helps.

How much did the motormount cost installed?
Thanks
