Fg Turbo Accelerating Issue

[FORCEDG6E]

Got a problem with my fg turbo zf six speed. While driving at a constant speed the vehicle sometimes incresease speed slightly and drops back like its hunting. Also does it with cruise engaged. Thinking possibly tps or something? Thanks

Have you checked coolant level and colour? If the heat exchanger on the side of the zf splits it can cause tranny fluid to mix with coolant and it gives the car a constant hunting feeling

Yeah mate coolants all good its not all the time only does.it every coulple weeks for about 1 minute

Does it do it when the car is up to operating temperature or generally within the first 10minutes of driving from a cold start?

If it's after a cold start - it's normal.

Nah does it after driving for a while I drove for two hours once and it did it for about 30seconds

mine does it to sometimes after some wot. next time when its happening just accelerate a little bit and see if it continues to accelerate for a second after. mine does it on cruise and in normal driving every now and then to.

will be interested to see what people say about this issue.

Yeah mine does it after some wot aswell. When its doing it I give it some sh*t it stops for a sec then does it.

No this is not normal cold or hot, my car does not do this.

You need to determine

1. Is it switching between 2 gears causing the change in speed

2. is the throttle plate moving which is causing the change in speed
