r8 auto sc problems
Discussion
Bargepole, dont and touch are all related to such an item.
Stick with the manual. Ive read about loads of Auto's dyning and seen the same myself.
Ask Mysty his auto is Ill with the SC. Other guys have died without any mods. Unless you want to spend some ££ on rebuilding it to handle the power.. Warranty is also highly questionable as its modofied so Vauxhall will push back hard if there is any issues.

any tips advice and problems encountered by fitting sc to r8 auto .need to know before buying one
Buying a vxr8 or buying the SC?If you already have the vxr8, just leave it as is, or sell as mentioned. Personally I would talk to Mysty as he is arranging a autobox upgrade. Maybe in a year or so when upgrades for the auto are proven and available then you can revisit the idea.
T42 does the 4 speed IIRC
You can get an independant controller, but the stock one is integrated into the BCM and ECU for torque management, stability control etc.
So you would be better off with a full manual powerglide and a manual tune
See the bottom of this page for what controllers do what trans

I had a few problems with mine, but nothing like the box going bang as I've heard has happened even in the standard car, here, in the US and Oz.
While at Santa Pod the autobox didn't want to change gear, the engine would hit the rev limiter and I would have to manually select the next gear! This has never happened when road driving even after 3 laps of the Nurburgring
There was suggestions that the box was somehow slipping when the car was on the rollers at the dyno day, but that may have been the supercharger belt.
The car has seemed a lot better after a service at Picadors where the old GM Dexron 6 transmission fluid was replaced with fully synthetic Redline Racing stuff.
My planned upgrades are: Oil cooler as fitted to the ls3, Walkinshaw have this for me but I'm also waiting for a new torque converter from the US, but the company (Vector Motorsports) seem to be now ignoring my emails! this was after I agreed to pay $300 shipping! TCM tune, I think this will help massively, there's good feedback from others who have had theirs done.
Walkinshaw also offered me a clutch pack and seals kit upgrade, this doesn't come in cheap but I managed to save some pennies over xmas so I'm not ruling it out just yet.
If you want to run s/c'd with an auto I would suggest new trans fluid, an oil cooler and TCM update at least, also driving with mechanical sympathy in mind wouldn't hurt!

so thats what you were doing after the last BTCC race at silverstone - driving round the carpark with mechanical sympathy in mind lol, I could have sworn you were doing a bit of drifting with the odd donut flung in for good measure

lol oh dear, you got me! I did keep it off the limiter though
tcm = transmission control module. You can tune, shift times, line pressures, torque management etc
Your main problem might be aftermarket uprated parts for the trans, its only just out so parts might not be available.
A mild tune up might help, but guys have messed up the trans badly because its pretty complex and can be in 2 gears at once, so if you mess timing and shift speeds up you can tear it apart. The knowledge will come with experimentation
I hope you have a large wallet.
