Tranny Issue

Howdy all,

New Boxster owner, new on forum. I've got a 97 Boxster with a tiptronic. When in automatic, after some hard driving or a while at interstate speeds, it downshifts VERY hard when I decelerate to stop or take off ramps or whatever. Sometimes it does it from 4 to 3, sometimes in 3 to 2. It shifts so hard the whole car jerks. Any help with this situation would be very much appreciated.

Thanks,
Maestro

Hey Teacher,

How many miles are on your boxster? and how many miles ago to you think the tranny fluid and tranny filter were replaced and how many years do you think the fluid that is it the tranny right now has been in the tranny?

If you think its been along time then you probably need to change both the fluid and the tranny fluid filter... cause you will get hard, late and agressive shifts when the fluid & filter are past there prime.

I was told at purchase that the 75,000 mile services had just been done, and I've put about 1500 miles on it since. So if the fluid and filter are part of the 75,000, then they've probably been done. I'll get the stuff replaced regardless, but what else could it be if that doesn't fix it?

At the very least, I would do the fluid and filter on the car. See if that helps.

or lack of ATF will do that... and soon your transmission will go bye bye
because not enough oil... check to see if its at the right level...

Yes, Automatics are very sensitive to having the right level of ATF and clean ATF. I would get your fluid and filter changed immediately.

Well worth the dough if it saves you the cost of a new TIP.

Good luck.

yes ATF= automatic transmission fluid

you need to not drive the car and figure out whats wrong first
because your tranny can go out quick especially you had been through with this problem for a while

I had the same issues, hard downshift and occasional slip when upshifting. Changed the fluid and filter, no more problems.
