TC lock is not stays on

[wagoneer]

The problem is that the TC will goes to lock about 55mph and everything looks normal. But soon I don´t accelerate the lock goes off. Then even little acceleration and the lock goes on and stays on as long I accelerating. And then off again. The OD will goes on about 50mph and stays on whit no problem.
:doh:
Wher to look the problem??

I have the DTT 3 disk TC and DTT VB as well.

This may be due to adjustment of the throttle position sensor.

Another solution is to add a TC lockup switch, you can use this instruction:

I have found that you do not have to replace the trans relay if you use a 50 ohm 10W resistor between the toggle switch and ground.

check your voltage at your tps, while key ignition on should be at least 1volt iirc. then check while you are driving, you may be loosing voltage while crusing, i dont remember what it should be while driving. i had the same prob. also check your neg battery cables. tps while is the orange wire in the loop coming off the tps, pos lead on it and neg on the neg bat terminal.

The problem was to TPS sensor adjustment. It have to be 126,5mm- mine was 132mm :bang Little adjustment and all works fine.
