Gearbox Ratios.

[crisisjez]

Hi guys, looking to replace the T56 I have in my Monaro with something a little more sensible for high speed runs and was wondering if anyone knows the ratios of the 6 gears in the Viper box.
TIA

Bernie at CTC might know (Competition Transmission Services) near Luton, I know he has worked on some of the Viper gearboxes

Not sure what is in the VX trans.. but i changed my stock viper ratios for the Aston martin 5th and 6th and they are much more usable...

Bernie (mate) did mine and a few other things while he was in there...
Give him a call as he has done a few VX trans as well.. Tell him Baz sent you...

Thanks guys, the Aston internals arn't interchangeable with the T56 but interesting that they are with the 6060? in the Viper.
Will give Bernie a call.

.63 6th
