I have contacted GDE about a towing transmission tune for my CRD. Since I live in Kommifornia, he is not able to sell me a towing transmission tune module. Does anyone have a GDE towing transmission module that they are willing to sell. It would be nice to be locked up in 4th gear since I am pulling a 3800 loaded camping trailer with my CRD. I feel bad for Keith at GDE, I purchased one of his Eco tunes for my jeep long before CARB decided to give them really expensive fines if they sell to anyone in CA.

See this older thread, it may be of some help to your delima?

Another option, either purchase a used TCM for a GC, Hemi Dodge, or Dakota or use your OEM TCM (if you don't mind disabling your Jeep for a week or two?) and ship it to GDE for the programing and then either get a friend outside of crazyfornia or one of the members on this forum to act as a middleman.
GDE ships your reprogramed TCM to another location (Non-crazyfornia) and then middleman ships it to you. Problem solved! GDE is in the clear and no one in crazyfornia knows the difference.

If you need help, PM me.

Just be careful. I sent GDE a Ram TCM I had and they were able to flash the non-F37 stock Jeep tune but not their own Eco tune. They had to send it back to me so I could swap it for my actual Jeep tcm.
