Overdrive Problem

6 posts in this topic

]Help!! Ive just spent £400 on having a gearbox solenoid changed and valve body pressure done etc to try and cure my problem - It wont go into Overdrive but other gears work fine, as does kick down-someone has suggested TCU but is it more likely to be a rellay - if so where the hell is it!! - Thanks and and replies appreciated

Why do you say it won't go into overdrive???

Overdrive is only 4th gear.

Hi Al

I had the same problem earlier this year, I spent the best part of £2000 having the gearbox re-conned, every solenoid replaced, clutches renewed, hire cars,etc etc, only to get it back 3 weeks later still with the same problem(the only thing i got from the re-build was an expensive 12 month warranty)

I then swapped the ECU from my other surf and b*gger me,it solved the whole thing. After spending another couple of weeks searching for an ECU with all the matching part No.s. I dragged my way thru eblag to find one,,,,, It worked out cheaper for me to buy a whole vehicle just for the ECU and then break the rest.

I eventually made a profit on the breaker.

So my friend, I believe your problem lies in the ECU

Cheers

Paul

Was the speed sensor checked?

Is the ETC button pressed in?

The ECU is on the passenger side behind the plastic panel near the door.
