83 240D tranny won't shift past 2nd gear.

[dmorrison]

Got the daughters 240D on the road but have some tranny issues.
A brief history. Bought the car in Feb. Slipped 2-3 and 3-4 and shifted early. Repaired all the vacuum leaks and the tranny seamed to operate normally.
Over the last couple of months rebuilt a bunch of stuff. Those items applying to the vauum and or tranny are the following.

Tranny
rear seal replaced, nut torqued to 120Nm
tranny fluid and filter replaced, to the correct level with the correct fluid.
vacuum lines detached and cleaned with brake cleaning fluid, dried and reinstalled.
tranny cooling lines to radiator replaced.

The vacuum system.
all lines removed and cleaned one at a time so they were replaced correctly.
air switches on top of valve cover, new cams and operation confirmed correct.
Vacuum pump to booster hose replaced.
All 1,2 and 3 way rubber connectors replaced.
All vacuum operating units checked and operate normally, except 1 door lock which is isolated.

The car runs normally except the transmission will not shift above 2nd gear.
Did a search and could not fine anything specific.
The scar will start in 1st and shift normally into 2nd gear, no flare, jerk,delay etc. But will stay in 2nd gear all the way up to 30MPH. when slowing it will shift into 1st in a normal maner.

I will check the black vauum line for 15inch of vacuum until full throttle then should go to 0 inches.
I will also apply vacuum to the modulator to make sure that the diaphram is not damaged, It should hold a vacuum, from what I have been told. If it does not then the modulator is the problem.

Any other advice??

When the car was purchased we antisipated a new tranny, but after fixing the vacuum leaks it ran fine. That was confirmed by a Mercedes mechanic who drove the car and by the Service Rep that I use at the dealer, who has a 240D. They both said the cars tranny was operating fine.

If the two items check out OK. I was going to bring it to the dealer for an estimate and/or diagnosis.

Thanks
