Truck goes Into limp mode Intermittently.

this truck needed a Tipm but couldn’t find one new (back ordered and 1300$) or used. Customer found a mobile guy and he wired in a external relay and fixed the issue. All data led me to the transmission control relay and stated its the pcm relay in the tipm. wanted to know if the relay is external or is the relay part of the printed circuit board

If it was part of the tipm it should have a dotted line around the relay instead of a solid line. Looks to be a serviceable relay.

I thought so too. I guess the wired in relay fixed it because the grounding for the relay is done internally?

All the ones we've seen have had the relay built into the TIPM and not replaceable. If it was external the mobile guy would not have had to wire in another one.
