Allison 5sp: Codes

[Tank01]

1300 miles on a rebuild for transmission and transfer case (due to pump rub). Replaced the ATF in my transfer case with Mobil 5/30 synthetic, hour later trans limped. Throwing C0055, P0842, P0847. Replaced spin on filter and reset codes. Limpes after trans is warmed up, runs ok when first starting (cold).

Any Ideas? Removed programer and running stock, still limps. Rebuild guy no longer returning my calls. I thinkg the Mobil 1 change has nothing to due with my current issues, but would like to hear from others if someone has had the same problem.

What year and what mods on the trans?

2004, upgrade on the clutches and Torque Converter.

Problem can be a bad pressure switch manifold, stuck valve or wiring at the valve body.

Talked to Mike, he suggested I reach out and ask "does anyone know a good shop" in Fort Worth TX area?

PM Josh H. I think he works at a diesel shop in that area.

There is one shop mentioned in here. It might be the same one that Josh works for.

Thanks to all who responded, special thanks to Mike L. for taking the time to listen to my issue.

I spoke with "Jim" @ Texas Performance Diesel, 903-473-1144, Emory TX (just East of Dallas). Super nice guy, looks like he'll be able to help me get back on the road, with out doing major surgey on my wallet!

Thanks again to all! :thumb::thumb:
