Hey guys. New member here first post so not to sure on how forums work or what not so don't mind a bit of help learning.
I recently bought a 06 bf xr6 turbo stock, and planning on doing some work to it perhaps getting it to 350rwkw in the near future, I know the zf6 has its own tech shop but I couldn't find the answer I'm looking for. The old owner of the car told me it was due for a tranny service as it's just shy of 140,000 kms now. I noticed when driving cold it seems to take a split second longer to change gears but once warmed up it's fine, however when it's warm it drives really well, only problem I had was I was doing a burnout (just the old but new car excitement) and as I came to shift in to second it jumped abit and speedometer went to 0 and kind of bogged out on power and stopped. After a second the car drove fine, no problems at all, now I know the battery is due for a change and the tranny is due for a service. Are those two going to cure my problem or could it be something deeper into the box, cheers in advance
