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: What are these two O-Rings that came with my new transmission?
These O-Rings are for you to re-attach the factory transmission cooler lines. If you have upgraded from factory, you can simply discard them.
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.
