I ran an '01 on my '04 LB7 for years. Many times I switched TCM's ( '01-'04 LB7 ) with cutomers to diagnose problems. Never had any issues.
come over friday
Not to derail, but James are you doing a compression test on your truck already?
yup, trying to figure out why im going through 2 quarts of oil every 2,000+ miles. gunna do a wet and dry compression test, then a leak down if i see no difference in the wet and dry compression test. Its not due to bent rods though! well, least i really really dont think so, anything is possible with my luck lately
thats great to know! the 05 5speed tcm wont work though correct? just 01-04?
I thought 05 had some additional solenoid or something?

G solenoid

The '05 will work but will throw a code for the G solenoid.
Not always. I put an 05 LLY TCM in my BURB and had nothing coming out of it except a LONG list of trouble codes. Flashed it to an 01 and it has been that way for over 3 years. The 01-04 LB7 TCM will swap right into any of the 5 speed trucks, but the LLY one can freak out is in an LB7 app with no G solonoid as it happened in my BURB. Then again that was in a stand alone type swap.
3500 max.
Dual fuela time :rofl:
If low rail pressure will make it hang a shift, why would my 4-5 never skip a beat? Just thinking outloud here.
I found the original DSP2 tunes the truck came with when I bought it. Going to load a bone stock TCM tune, and the DSP tunes and go drive it and see where we are at. I dont ever remember it shifting like crap when I worked on this truck previous to me buying it. With my 20% tips, I dont think Ill have a roblem holding 2300Us on the "big" tune.
Not sure I don't have a log of that... As the rpms come up slow (4th and 5th) the truck is not using as much fuel as quickly.
Can you post a log of that?
Doubt it will be much better as the tune you are running now is around 2180Us. Try a NON DSP file and see what it does.
CP3 may be an issue then. We have logs from only a few months ago of it holding 2700uS on 30% injectors, and it was supposedly recently replaced.
