2.93 to 3.29 gearing change

[TurboTPI]

Has anyone here done this gearing change? If so, whats the best way to adjust this in hptuners? I work with a guy that has an 04 CompG, i was just going to apply his trans tables to m y tune. Is that ok? I read somewhere today that that doesnt work for some reason

Sometimes HPT will have your 2.93 car listed as 3.29. If it's 3.29 already then list it to 3.69, if it's 2.93 then put it to 3.29. Done and done.

Are you talking about in the gear/tire wizard window? Cause i cant find final drive ratio anywhere haha

It's been ages since I used HPT to tune a 3800, but I remember it was in the trans tables tab There's probably been 5,000,000 updates since then so who knows where they tucked that away now.

Pretty sure i found it, thanks man. Glad there are still some smart dudes helping us out on these dying platforms

Yes, make sure the transmission file is completely stock and do that change. They moved the gear/tire wizard, but sounds like you found it. You might need to re-enter your tire size too.

Comp-G package has 3.29 gearing from the factory. The regular GTP has 2.93.

yeah, it is moved to the "Edit" drop down at the top of the page. I entered 3.69 and auto adjust. All good now, shifts and TCC are back to normal. Thanks guys. i think im going to really like this gearing for a daily that is mostly driven in stop and go traffic haha. Feels damn good so far
