You know the hexagonal standoffs I'm talking about. So there's the adapter plate that bolts to the CP3, then that whole assembly bolts to the block. The three bolts that fasten the adapter to the CP3 have some hexagonal standoffs. In fact, there are a few Ebay listings for these bolts. I'm...

I don't understand the engineering reason why to use standoffs. Anyone know this? Can you use regular hardware?

First, thanks for all the help. So to be clear, to make my 1991 rebuilt 4L80e (has updated internal harness but old Bosch force motor) operate correctly with a T42, I most likely need to swap to the newer force motor, correct?

I think I have a dilemna... Again, my trans is a 1991 and was rebuilt 12 months ago by a reputable local shop. I'm assuming they didn't swap valve bodies, but do you think they most likely updated the force motor, harness, and plugged the line pressure damper circuit? I ask because I wonder...

So I have a ECM from a 2006 Silverado HD but haven't located a T42 yet. Do I need to hunt down a T42 from a van, or can I simply buy a new, unflashed T42 and flash it using EFI Live or can I get away with a used T42? My overall plan is to put the stock van tune on the ECM and then put the...

Okay, that sounds reasonable. I've studied the diagrams and I'm not confident I have identified just exactly how the ECM and TCM communicate? Is it simply via two wires (GMLAN + and GMLAN -)? I've looked around for a van harness to no avail...

So what about using the LBZ apps signal with a modern standalone controller? The install instructions on US Shift and Compu shift both say to tap into the apps signal. Do you agree that would work? Isn't the apps just a potentiometer with 0-5V signal?

Thank you. After reading several posts between you and BillyG38120, it sounds like a standalone controller like US Shift is damn near impossible for my trans, correct? Because all the current controllers require a Holley force motor, does this mean I need to swap out the entire valve body...

Hi BillyG38120 Hi there. I see i where you offered up help to a guy with programming his pre-1994 GM transmission controller. Are you willing/interested in helping me with a similar problem? I'm happy to pay you for it. I have a 1991 V30 that I recently put a Duramax 2006 into. I'd like to...

Hi billyg38120 I see in a few other posts where you offered to help calibrate/tune a stock GM TCM. Would be willing to help me out? I'm willing to pay you for this help. What I have: a 1991 V30 with a 2006 Duramax LBZ engine.
