Turbo Transmission into C4s

Can someone chime in please and tell me if a 02 c4s Tranny is the same as an 02 Turbo tranny. I'm having issues with second gear, does not want to stay in second. Thanks

Turbo trannies wouldn't fit in a C4S, since it has the standard Carrera Engine...

Had similar issues with mine, ended up having to replace Syncro and Gear, as well as clutch and flywheel...

I understand it's longer than the c4s tranny but will it mate to the block and could you use the Turbo Clutch. Has anyone done this?

Nope, this will not work. They have different bellhousing designs and are not interchangeable.

Your issue however with the 2nd gear pop out MAY have a fix that will not break the bank, although even if you have to rebuild the gearbox it will only run about $3500 or so.

Let me know if I can help,
