these transmissions will handle the power but it is important that the transmission have the transmission program altered to accommidate the extra power as the existing program adjust pressure according to load and throttle to suit the factory power range .Alter the power and the transsmission will not responded to the extra modified performance hence startes to slip and eventualy fails.As these are electronicly controlled the program has to be altered accordingly.Have seen this all to often and the tranmission gets the blame but it is the program that causes this.There are piggy back e.c.u.s that can be puchased ,have encounted them before but could not say where purchased try google to find

c9/c10 3speed all the way have had it for a year and cant imagine anything else for the street

The 4spd can be built to be reliable around the 300 mark, it just depends on how its tuned, what parts are used and how the box is treated. Make sure you get a transmission cooler too, this goes a long way to saving the box.

You are north of sydney, so maybe track down Dominello Transmissions, they have a very good rep with the BTR

ok so obviously the 3spd is only good for street not highway... correct?

and I'll be searching for around 400 oneday so I dont wanna be rebuilding it all the time

[bda12pleaseu]

so how much power can the c10 handle and what is involved with this conversion has it been manualised

hi all,

just wondering if anyone knows what wiring changes are required to accept a t56 from a 4spd auto.

Hi Cameron. Mine did the same 3 times because of a dodgy tune from a tuner in sydney! Get the tune right, and get some extra clutch packs thrown into the C1 (3rd to 4th), get a cooler and drive it sensibly and it will be good for 300-340rwkw. Check out my sig for details on tuner and box builder.
