My son, a student at Virginia Tech, has a 2006 Saturn Ion with about 86,000 miles on it. He came home for the holidays and so far we’ve:
- Replaced all four tires
- Put new brakes on it
- Replaced the passenger front rotor
- Replaced a wheel bearing
- Replaced one of the O2 Sensors
The car is presenting with an opportunity for a transmission shop boat payment but, we’re looking for an opportunity to make another tuition payment so…
Here’s what’s happening:
Intermittently, when we approach 40 to 45 MPH, instead of shifting into what I would assume would be 4th gear, the automatic transmission seems to shift into neutral. The RPM’s rev up until you take your foot off the gas and it won’t shift back into gear until you slow down to about 30 or 35 MPH. When it does shift back into gear it seems a little ‘clunky’.
We put a code reader on it and the computer has presented with P0700 and P0757 (possibly P0756 as well). It seems like when you clear the code from the computer the issue goes away until it happens again but, we haven’t had it out of the shop long enough to confirm that theory.
It’s currently in the shop (our local garage - seems like a good bunch of guys). They’re going to try a new “TCC switch” and possibly cleaning a screen or filter but they haven’t had time to do it yet so we’re not sure if that’ll work.
My son left this morning in his mother’s Prius complete with the little stick figure family stickers, “VT Mom” sticker, and other emasculating paraphernalia across the back.
Anyone have any idea what the fix might be?
