Automatic transmission to manual conversion

[57jam]

Hi all,

I thinking of carrying out a automatic transmission to manual transmission conversion,  using the automatic ecus but rewiring the neutral switch to clutch switch, reverse switch and speed sensor.

Will this work?

Thanks.

Maybe, you probably need to leave the auto TCU in place so the ECU doesn't through a huge hissy.

However, the ECU wiring will be the least of your hassles, search for threads from others that have done it, it is a huge job.. just sell your auto and buy a manual V35!

Hi, the car is rare over here in the uk and 90% of them are automatics.

Fair enough, but I suggest you do your research first so you know what you are in for

It’s very easy I did it in a 250gt!! 

Get the gearbox, pedals, clutch slave and tail shaft and bolt it all in and wire the neutral by pass up and all good. 

Did a mix and match between the coupe and the original tail shaft, split in the middle and then had the rear holes drilled to suit the diff as the 250gt has a smaller diff than the 350gt and had it balanced. 

Yes you will get a auto warning light on the dash.

I thought relocating the park brake was one of the difficult tasks, with some people cutting and welding part of the tunnel from a manual to get all the hand operated park brake to function properly?

Maybe, mine was in race car so it all went in the bin

have a read through this -

was a CVT, but most things will be similar, somethings will be more difficult as some of the transmission mounts for the CVT were the same as the 6MT, but not the same as the conventional auto.

cheers, that was a good read!   My biggest problem is I just can't find any parts/any breaking in the uk, I know some parts can be used from the 350Z but it's the drive shalf, hand brake and trim which is a problem.
