transmission shifting problem.
I have all the related problems of a maladjusted vacuum system, which I am going to address next weekend, with the help of this forum, but I am unsure if this is also related. My transmission will not shift into high gear until I am going 65 mph, regardless of throttle position. I do not want to drive it due to the high rpm's which I'm sure diesels are against. I have to work this weekend so I will be unable to work on it this weekend, but I was just wondering what you guys think. Could it be a throttle linkage problem?

P.S. the car is a 1981 300D.

What's the 1-2 and 2-3 shift points?

the 1-2 shift is early at around 15 mph, and the 2-3 is around 35-40 mpg. The shifts are hard at part throttle but smooth out at full throttle.

The 2-3 is at 35-40 with very little throttle? If so, then it's also very late.

I thought these transmissions usually shifted at certain setpoints, and the vacuum system adjusted the harshness. I realize throttle position will affect when the car shifts also, but this car shifts the same regardless of throttle position.

If the throttle has no effect on the shift points, then the Bowden cable is not properly connected to the linkage or it's jammed in some fashion.........the cable regulates throttle pressure internal to the transmission and the increased throttle pressure serves to delay the shift.
I believe that vehicle also has a Bowden cable and that's the first thing to check. |
