The ignition switch was free, the pressure switch wasn’t awful, but if the pressure switch hadn’t done it would have been TCM time, and that’s $1200ish for the TCM (from GM), +400ish to get it flashed for my VIN. The Allison is apparently very finicky about the voltage it wants to operate off of.

These transmissions will warm up when towing or driving in the summer months. 200-225 is very common when the ambient air temp is 80-100 degrees and your transmission is under an increased load. Temperatures from 230-240 have been reached with no damage to the transmission.

Can a Allison trans injector last 100K?

Injectors may not last 100k or even close to it. Some guys fail them at 30k and others at 200k. I wouldn’t worry about the trans, if you do have to rebuild it. Get a performance build from an Allison Guru, your traditional transmission guy won’t be the right guy for this build.
