Re: Tmaxx not shifting

Most of the time when it won't shift into second it's because it needs a tune. Rpm's aren't getting high enough to shift it. You can adjust the shift point mechanically as well, refer to manual available at Other than that it could be a mechanical issue but most likely I'd say it needs a tune.

Re: Tmaxx not shifting

If your high end needle is too rich, you won't reach the required RPM to shift into second as already mentioned. There could be other issues as well but this would be the first and easiest to check.
