I can try skipping the tcm tune I haven't tried that. I always just did modified stock but never fooled with the preloaded settings. I'll try that and let you know.

Got the 87 oCtane canned tune loaded no changes. Skipped tcm tune all together as requested. Still getting the banging shift at 100% WOT. I'm really at a loss now. Although I understand the PCM and tcm work together to find the proper shift points/pressure I'm not understanding what's going on here. Does it without any throttle boost added on my end.

Would really like to get this thing working properly so I can have the extra power as I'm putting a small lift and larger tires within the next 2 weeks.

Would my issue possibly have anything to do with my drop in k&n intake filter? Just a factory replacement not a intake kit.

OK, did you restore then reload and skip the tcm?
if not whatever you last loaded to the tcm is still there....

No issues whatsoever stock. Shifts nice and smooth under light and heavy throttle even pulling heavy loads even 100% WOT, no issues whatsoever. And yes I restored original tune then installed just the PCM tune and skipped tcm tune install.

OK, we're on to something.

Post the current files from the tunes folder and the current info file please.

They are posted previously in this thread. Nothing has changed. The truck is back on factory tune for now. I believe the file I uploaded previously had +15% throttle boost.

OK, Im not trying to give you a hard time, but would you please post the current files from the tunes folder, and the info file?

If you restored and reloaded Id like to see whats there now.

Thanks

Jeez y'all have a spambot issue on this forum. Thanks for deleting all the unneeded garbage in this thread. Any update on my issue?

Post by **mikel** » Mon Oct 26, 2015 5:20 pm

first to 2nd seems fine all other gears still bang pretty hard at WOT.

Post by **mikel** » Tue Oct 27, 2015 10:08 am

Hmm...I will need to look at the files, ALL I changed inthe tcm tune was to let it shift a little harder for 1-2, didnt touch anything else...
