Got a problem with the autobox, its holding the gears for too long, for example it will stay in first and second at the same rpm for like 5 seconds at a time (seems like an eternity) before shifting up. Now chunk reckons his did this and it was the autobox ecu playing up.

However, the car has a speedo chip fitted which also effects the steering.

Could it be related to the speedo chip messing up the signal? Also is there a way of wiring up the speedo chip so that it doesnt mess with other things apart from the speedo?

 

From what i can gather from the steering at least, the speedo cluster electrics has an effect on it. If I just unplugged the cluster would everything work as if the chip wasnt fitted, or would it mess up because it isnt connected at all?

 

Thanks

I could be way off the mark here but I seem to remember a dodgy TPS could cause that.

whats the make and model of your speedo conversion chip ?

not sure, maybe john dixon knows, got it from him.. John?

 

vijay, yeah might be that, autobox diag doesnt show it as a problem but I guess that doesnt mean anything so long as the output isnt outside acceptable range. A conZult diag would be pretty useful, any kind people in the midlands have a conzult and willing to run a check on it for me?
