Shift Kit

[milehibry]

Just bought a 2005 B4000.
Fun truck, needs more go, but 5.0L will wait til next Summer.
Question is:
Does any company(aftermarket I assume) make a shift kit for the 5 spd auto trans?
I'd like to be able to shift it manually or let it do the work.
ANY ideas?
I searched the forum, found nuthin.
PLZ help!!

No performance kits that i am aware of. I like the Sonnax zip kit for the 5R55E and 4R55E. Superior makes good kits as does Transgo. All address the same issues that are common to these models. I belive you could also have a 5R55S in that model year also. Quick check is dip stick or no dip stick.
stick = 5R55E
no stick = 5R55S
These kits simply make a worn VB continue to work for a while longer. No change in shift scheduling or shift perfomance.
