47/48RE FAQs

 
Q: Is there tuning for the 47 or 48RE?

No there is not. While the valve body is electronically controlled, there are no parameters that can be changed via software.

Q: Is there a re-learn procedure for the 47 or 48RE?

There is no re-learn procedure for these transmissions; however- you must let the transmission properly break in before feeding 'er the onion. We recommend a 500 mile break in - with a mix of city and highway driving that will let the clutches bed in properly. No towing before 500 miles.

Q: Can I put a Full Manual Valve Body (FMVB) into my stage 1 or 2?

This is not recommended. FMVB's are meant for drivers who are using their trucks for more performance based scenarios- such as Dyno, Drag Racing, Etc) With the increased line pressure our FMVB's create, having one installed in a stock/stage 1 may result in a broken input shaft- if not billet.
