95 E320 1st to 2nd shift point adjustment

Also posted this in performance thread but thought it probably falls into this catagory also.

Just had reman. trans installed and I am trying to adjust the shift point from 1st to 2nd gear at full throttle. My old trans. would shift around 6200 RPM. Now it shifts at 5000 RPM unless I hold the shifter in 2nd. Also, once I am rolling, it will not downshift from 2nd to 1st no matter what. Not good for those "whoops!!!" situations when I need to get up to speed fast. I tried tightening the throttle pressure cable but this only seems to have an effect on 2nd to 3rd shifts. Currently it goes from 2nd to 3rd at 6400 RPM. I have also noticed that when I place the car in drive, it requires more throttle than with the old trans. to get moving. It scared me at one point when I gave it about half throttle from a dead stop and it felt as though it was slipping a little then fully engaged.

Any thoughts or recommendations are greatly appreciated.

The full throttle up shift adjustment is on the Valve body. Any adjustments will raise ALL the up shifts.


Any full throttle kick down up shift, should happen just under red line on your tack. Your owners manual will have the RPM number.

If you have a problem with the 1st to 2nd full throttle up shift only, it could be valve body related or 1st gear (B2) is slipping. The delay movement may also be the result of a problem in the B2 system. With the wrong torque converter stall speed, to high, you need more throttle from a stop to move the car, thatís another possibility

Take it back to the shop that did the work.

Thanks for the information. I spoke with the shop that installed the trans. this morning. They think that an older model valve body was installed. They also stated that they could adjust the 1st to 2nd full throttle shift point by adjusting the spring in the valve body. They are going to swap the valve body, let me drive it around, and make any adjustments until it is the way I like it. Good people. I an taking it back Friday and will post the results!

All fixed! I went back to Sun Valley today and Mark said that the problem appeared to be that something was stuck in the valve body. They poped on another one and the car is perfect. The car now starts in first gear, 1st to 2nd full throttle shift is at 6200 RPM, no slippage when starting off. Could not be happier.
