I have a truck that we swapped an LT4 with 10 speed into and did not have the original ECM and TCM. I purchased a new E92a and had the LT4s VIN programmed into it with GM software and purchased the unlocked T87a from HPTuners with the same VIN that I used in the ECM.

Since I do not have the original TCM, can I just plug in the unlocked TCM without following the replace TCM process?
