Problem Reports

We have shift problems when we are driving down the highway. it is like the engine is having to work harder to keep up to highway speeds. It will get up to 60 Mph but anything other than that you have to hit the ECT button and then the engine revs very high like up into the 5.2k rpm. I have changed out the tranny fluid and the filter and it does shift ALOT better now but still has the problem of running or keeping up the speed on the highway. ie 70mph.

truck periodically will not shift into drive at initial start-up. Will very often shift fine after warm-up. Occasionally will not shift into next gears without letting up on the accelator. Drives ok some of the time.
Took to dealer and they said transmission was beyond repair - they have no parts for it - it has the A340 transmission so I'm puzzeled that this tranny is not reparable??? Or is the dealer pullint a fast one to have me purchase a new transmission at what would end up costing more than the car is worth?

Just noticed today it takes more rpm to move off the line, hard to tell if shifted into 2nd, acts as if slipping in 2nd. This just happened... I'll report problem & solution after consult w/mechanic. Using synthetic oil. I checked oil, it is ok. Very puzzled.

O/D warning light flashing at non predictable intervals. also pressing on gas pedal at a stop light and not having any power. not currently fixed but will be very soon (just found out what it is).
