Had a shop install new Dana Sipcer Gears on my Rig. (Recently put on 37s)….
Reputable shop, informed that installation went good. They updated computer with JScan. During test drive, informed that clutch heat light went on, ultimately service trans - Truck ended up in Limp mode.

I had similar issue happen when I used Tazer for my tires. Ultimately learned that it was caused by user error. Anyhow, after dealer checked, cleared code and got my truck running normal, I was able to use JScan. ALL GOOD.

Still at the shop - which sucks, being long weekend and all… they are going to try to figure out on Tues.

Wondering if anyone else with a manual has run into this issue. Do they have to take it to dealer? …. Any thoughts / suggestions would be appreciated.

TY!

Very suspect that same / similar issue happened after regear. Of course, assuming not an installation issue … Hoping I can pass along some suggestions to shop.

Well, turned out to not be a huge issue, besides not having my truck for the long weekend. Oh well.

Shop was able to spend some time with JScan and resolve issue. Hopefully.

All is well for now :)

I love that people have to use jscan , an aftermarket program hack, to correct a manufacturer programming issue. Ridiculous.
