Cat 3126B transmission question ⁉️

[290smallcam]

Was looking at the wiring schematic for 7AS prefix, CAT 3126B. It only shows hook ups for a AT,MT and HT Allison trans. This is a 70 pin ECM. Can the newer Allison MD3060 be connected.

The 3126 is backed by a 3070 in the A1 FMTV trucks so I would say yes.
Thomas bus' used the same configuration

Was just googling again and eeeerrrrrr! Hate that I can't find answers. Finding school buses with AT545's. I'm thinking the 3126E models, not B models use the MD3060's. Maybe someone on here has a M1083A1 with a B model Cat, 70 pin ECM. Wondering how the MD3060 would hook up to the 70 pin ECM on the 3126B Cat?

You obviously have no clue what you are talking about.

The 3126E was a one year motor in 2002. There are 2 prefixes for that motor in regards to thr HEUI pump.

The MD3070 and 3060 are the same 3000 series transmissions. 3060 is a 5 speed but can be unlocked to a 6 spd and the 3070 is a 7 speed. WTEC 2 or 3.


This has been done. All on video. Into an F350
