6.4 w/ Newest Update Problems

***Power Hungry*** · #1 Sat, August 8th, 2009, 02:14 PM

Couple questions...

Are we dealing with an EGT issue or a shifting issue?

In what level(s) is this occurring?

Current ECM/TCM strategy? (Check in Version Info)

Current Firmware and Calibration versions? (Again, Version Info)

In regards to the shifting concern itself, please define "not shifting very well". Shifting early? Late? Too soft or slipping? Too aggressive? Which shifts? (1-2, 2-3, etc.)

Thanks.

I was the one who talked to you on the phone two weeks ago and had the higher egt's and trans shifting problems. I have been running the older calibrations and have had no problems since. My shifting problems were 1-2, 2-3 it seemed it did not know what gear it wanted to go into, then when it would shift it would clunk into gear pretty good. If you need all the info on teh truck again just let me know.

Thanks for the help!

Shifting

4

Current ECM/TCM strategy? (Check in Version Info)

Just updated these today

ECM 8u7acg (This was different prior to today)
TCM 7u7aab

Current Firmware and Calibration versions? (Again, Version Info)

Firmware 3.2.596
Calibration 1.2.681

Update on this, I went back to stock because of the tranny issues two weeks ago. I then had issues with a EGT issue (stuttering) and White smoke at Stock. Known TSB. Truck is still at stock but would like to know if I need to update the Gryphon. Thanks.

We are readdressing these calibrations again. The L30 calibration series (of which 8U7ACG is part of) has offered a significant improvement over the last few series. We do have any update available that was released on 09/14 so you'll want to download that.
