trans has the gmr 1" chain 3.29 ratio and a unknown reluctor wheel.my car is a gt so it came with 3.29 stock,yesterday i was driving with my gps and i noticed that the speedo was like 7-10 mph fast i've put like 3k on it this way i didnt know it was an issue.When i screwed with it in hp tuners i ended up with like 2.80 fdr to get thew calculated down to 1.0 in 3rd but even then the speedo was off what is the proper way to fix this
nvr mind i fingered it out seems that the transmission had a reluctor wheel with 34 teeth on it so you could run a 3.29 ratio in a gtp without tuning.i used the excel calculator i found on here to correct my vss pulses and then since i had 3.29 stock all of then all the heat, line pressure and speedometer problems went away long story short if you buy it used know what it has in it dont assume

The accepted protocol on this forum is that if you post a problem, and ask for help, you must post the solution - even if you figured it out on your own - so that others may benefit. It's good manners. Otherwise you may find that your subsequent posts are ignored.
