ECM controlled exhaust brake on 04.5 auto?

Finished last weekend with the install of the LED showing torque converter lockup and cleanup of the wiring. I can definitely feel the EB come on in 4 and the 4-3 downshift. I feel the 3-2 downshift but the EB usuallly shuts off at 25 mph. Slowing down for turns, I feel the EB on in 2nd but it does not slow the truck down much. Probably what you mentioned experiencing until you installed the triple disc TC.
I really like the change in shift points. I don't need to lock out 4th in the city anymore, the trans now shifts up at higher RPMS and stays in 3rd until about 55 mph. It was a lot of work but a good chunk of that was self inflicted. Thank you for your help! Much appreciated.

Awesome that it works for. Enjoy

Isn't it fun to finally see what the TCC is really doing and if it is locked or not.

Last week I took the truck on a 1400 mile round trip from Southern California to Northern California. The exhaust brake and downshifting was fantastic. No trailer connected. Thanks Ozy!
