'05 GC won't hit 5th gear/lockup until 75mph..??

The trans tune you posted had considerable changes done to the lockup logic, all i did in the attached tune here was set that back to stock, everything else was left as is.
This was the custom cmr tune you posted right?

but did you get any custom tunes from any CMR tuners?

Yes. That was the last tune written. As I posted earlier this happens on the canned tunes, the CMR, and with the stock trans tune on the Intune. It does not happen when the intune is removed completely and or I'm running the Superchips. It has lead me to believe its something with the Intune itself.

Why would it not hit 5th until 75+MPH and then when 0% throttle load and coasting down, it will downshift into 4th around 68mph?

ok, bu the changes in your tune were not something we do, and would cause your issue, so can you load the canned tune, reset parameters, and export that so we can see it.

You want me to load just the stock canned tcm tune? The one Johan posted or the Performance canned tune? After that tune is loaded I post the LTW again? Seems kind of futile when I've told you its happened on all of the intunes canned tunes...

well I cant fix it if we cant see it.

please do so if you can.

Ok which tune specifically would you like me to load?

Post by **mikel** » Mon Feb 13, 2012 2:28 pm

the preloaded tcm perf tune

Ok, so just to clarify I would load the pre loaded tcm performance tune and then send that to you as the LTW file?

ksrracer · Post by **ksrracer** » Mon Feb 13, 2012 2:48 pm

Just want to make sure I post the right file. Thank you in advance.

Post by **mikel** » Mon Feb 13, 2012 3:44 pm

Yes, thats correct.

Thanks

Johan, retracting post, did not mean to cause trouble. I apologize.

hope this Jeep's issue can be fixed easily.

We only write calibration data, so there cant be changes outside the tune data.
The last tune written from an inTune is an actual copy of what was written to the TCM, so you can see exactly what went in.

We are investigating.
