aftermarket tech 2 question
ive been debating whether or not to purchase one of these units. heres what im encountering... my trans wont shift under wot from 2nd to 3rd until I let off. I may have a trans going out however I was told I may need to lower my shift points (mph/rpms) . does this tech 2 offer this capabiltly? thanks in adavnce

I believe you can alter shift points using Service Programming System function of tech2 'tis2000' or the newer 'tis2web' application however unless your c5 has been heavily modified I would say you have some other problem that requires proper troubleshooting, rather then reprogramming the system to shift differently from which it was designed.
Have you pulled the codes?
As a side note:
Before you fork out for a tech2, consider an MDI clone or vxdiag nano adaptor, which is cheaper and less susceptible to failure.

yeah I agree, im thinking my trans is a goner. it does shift fine at part throttle tho. no codes in the trans control module... my car is mainly stock. this issue started since I purchased it used (99 c5 w approx. 85k) I would used to just barely hit the limiter during 2 to 3 shifts, then last time I took it out it was hitting the limiter hard.

Some of the mdi clones come with the cracked software.
