upgrade..shift limiter

Reviewed By Jeff T (Milwaukee, WI) Reviewed for a 2003 Chevy Monte Carlo —5/27/2012 11:41 PM

required upgrade before use. installed disc, then during final installation, malware notice popped up and wouldnt install. had to remove spyware blocker before would work. malware notice still on laptop.... :( took many tries to get the right combination for the car to run and shift smoothly. still hits rev limiter from 1st to 2nd gear sometimes. notice difference right away though, especially shift firmness, has to be the best upgrade from the whole thing! during install on car, shows interruption sometimes, then restarts upgrade. very odd
