Just FYI, I have all the respect for what Bobbie did (I purchased his book when first offered)
but all that extra work and keeping the OEM PCM just to control the glow plugs is not necessary.
Delete the PCM and get a 93 GPR or rig up a switch on the existing 94-up GPR.
Way less wiring and splicing.
Thank you. I'll leave the ECM for someone else but will get the brackets and VSSB.That TCM is for a 93 and earlier 4L80. I see you have a 4wd.
The 16196390 TCM for 94-up was never used on a 4wd, except the Hummers.
I think the Hummers have a special PROM that accommodates 4wd.
The problem is the ..390 TCM cannot do low range, otherwise it will work with 4wd.
You may want to get an aftermarket TCM.
That VSSB is worth keeping. Your 95 already has one.
The NEW TCM you get is what controls the trans and only the trans.
The original PCM will not control the trans without the DS4 IP hooked up.
The only thing the PCM is controlling with the Bobbie Martin method is the GPR.
Wouldn't that make it a non-turbo 6.2?At least a 94 if not older. I bet it's a 88
Depends what the previous owners have done.Wouldn't that make it a non-turbo 6.2?
