Transmission and tuning.
 

Emailed Bill with no response so I figured I would try here. I have a dumb question. I recently bought a truck and the PO had the E4OD rebuilt by a local transmission shop. He had an upgraded transmission cooler added, billet torque converter, and supposedly some valve body work done. I think I should run custom tunes (I plan on getting the Phoenix). Should I contact the shop that did the work and find out EXACTLY what they did or is this enough information for you? If I need to ask them questions what do I need to find out for you? I plan on ordering my chip this week so hopefully we can get this worked out. Thanks a lot for any help you can give me.

I would bet that you should get the shop to tell you exactly what they did... 2 reasons, 1: it will make tuning easier, 2: It will be good to know for the future.

Okay so I am assuming that that means that I need custom tuning? Also what do I need to ask then? As in, what they did to modify the valve body and what not? Just so I ask the right questions, and get the right info. Thanks for the reply.

I don't know if you need custom tunes or not... but they will never hurt to have. I would say that yes, figure out what they did. There are a number of things that they could do so yeah, ask exactly what they did, if they installed a kit or did modifications in shop, or see what else they may have done.

The billet converter is of little importance. If the rest is just a minor valve body mod or shift kit, the standard tunes will be fine. We have tuning that already supports simple shift kits and those fall under the "standard tunes" category.

Thanks for the info! I will be ordering my chip soon then!
