You have a mismatch of tcm and ecu. [email protected]
Its not problem, sounds like you need to flash the 6l90. The 6l80 and 6l90 use the same TCM part number. You can flash it with hptuners
Try this142833
Please report back if this fixes the issue please
This is works for gen v truck and car os just like factory. No TCM programming needed.

I need a t93 cloned
I have p2805 code, transmission range sensors not plausible. Any idea what I need to do? The t93 transmission harness has no prndl wires like a t87 would
Yes
My t93 came in today. I could write an entire and calibration just find and that was with a e92 controller. Unfortunately i can not get the tcm to get the trans out of limp mode. I have a prndl...
I can't read even with the tcm and matched ecu. There is something wrong with the software. 1500$ to unlock and license and no trans data is showing up.i am trying to get a 2019 10 speed to work with...
Delete the low pressure fuel codes. There are three. If not running a low pressure sensor delete them. Never delete a fuel rail sensor code. Completely different. Next the 335 code is an issue. Do...
Unplug the maf. If it runs your maf is installed backwords
I can do it, email [email protected]
Pin 57 needs 12 bolts applied with brake. If it is still being weird make sure you do this test with engine running. The last fix would be to do a pull down resistor incase the circuit is not pulling...
Hey man sorry for the rough times you are going through. I can help with the swap. Check out swaptime on youtube. A earlier style harness and e92 can be made to work to run the L84. The big...
Is this in a jeep conversion? If so it is 100 percent being caused by the vendors cAn bus conversion module. I can?t spill the beans as I put a ton of time fixing this issue in our own module....
Hptuners can not program a new blank module. The gm tis service must be used with a special programming cable.
I?ll get a log off both of the Lt4 swaps. One is a cammed l83 Lt4 and the other is that stock Lt4 . Both had the issue
That fixed it!! Thanks so much! Why do you think it sets the baro code when using the stock baro in the mass air flow sensor?
This is in a swapped vehicle. The baro is broken out and is in the supercharger by the throttle body. I dont know if this is the correct way of doing this. I am using a 2018 truck OS running the...
This is driving and idling great but I keep getting baro codes p2227 and p2228. How do i tune this properly for the codes to go away? These can not be deleted or bad things happen...
I delete the codes for ambient temp
Are you running LT4 adapter plates to bolt it to the cylinder head? They usually leak vacuum and cause this issue due to the bolts being too long
You can not use a t87 on a 18 and newer 8l90. The internal prndl is different and the tcm will not work. A t87a must be used on 18 and up. In 2019 the changed part numbers on the t87a and it needs to...
The issue is Rpm extreme programming of their can bus module. 2018 and up transmissions go to limp mode because of the module. I went thru this on our own development. The only fix is for rpm to...
You need to run the proper l83 ecu with matching transmission. Next it’s critical to run the proper size air intake tube on these. Once this is done it will run like a champ
