Shift Points on Volvo S/V70 T5, Interesting Discussion

Shift Points on S/V70 T5

Hi, my T5 shifts very high in RPM in first, at low foot pressure it shifts around 3-3500 rpm, moderate acceleration can leave it in first until redline. All this while in economy mode. Any thing I can do to reset this? Thanks all.

“Just read this post. Under normal throttle, which I am usually a little light on it, I’m shifting around 2,300 to 2,500 rpms. If you are going above 4,000 rpms under normal pedal effort, I would think that you have an issue with your throttle body switch, linkage, cable, or something in that area/system. If the tranny is hitting all of the gears I would hope it is ok.

The TCM‘s prior to ’99 are not mated to the ECM’s. Also, that “car learn your driving style” stuff didn’t start until they dropped the E – S – W buttons. That system was pretty passive and had suttle changes in the shift points. From what I am reading, your car is shifting like it thinks your throttle position is near WOT.

If you can get your hands on a scanner that can read live data, see if you can read where the computer thinks the throttle position is. If you are at 20% and it is reporting 80%, there lies your problem.

In the mean time, check your throttle cable linkage to make sure it’s not hung up on something.”
