Happy Holidays Guys and Gals!
I've did some searching here, and not really found the answer. 2003 Tahoe 5.3 swapped in a 1986 IROC with T56 six speed. If I set the ecm to auto 4L60e the cruise works great. I have the TCC ran in series from brake switch to clutch switch and ran to pin C! 33. If I set the ecm to manual, move the same wire to C1 pin 35, no cruise. I even tried sending it to both pin 33 and 35, and still locked out of cruise. Is there a secret I'm missing somewhere?

Changing the transmission type will do weird background issue like this, so it's best to leave it as a 4L60e and disabled all the trouble codes for it.
Or start with a factory manual file from the beginning.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Yes, I do understand. I did disable the codes, the only thing that really bothers me a little, is the idle. When coming to a stop, it has a weird way of not coming down to idle as quick as it does when ecm is set to manual. Thanks for the reply.Originally Posted by 5FDP
