I did many mods such as pulley, headers, Magnaflow exhaust, trans mods, changed coils, cooling fan sensor changed, better fuel pump and had the ECM recalibrated. The Bonneville is way heavier than the GP and I made a pass with sticky tires and went 13.65.
There is a lot of aftermarket parts out there to make one go pretty fast.
There is also a link for the Factory GM racing Manual for the 4T65 Trans:

For my trans, I got the trans from Trasher:

Right.
What I said... From Wiki :
The 4T60-E (and similar 4T65-E) is a series of automatic transmissions from General Motors. Designed for transverse engine configurations, the series includes 4 forward gears. The 4Txx family is an evolution of the original Turbo-Hydramatic 125 transverse automatic introduced in the late 1970s.
The "-E" transmission is electronically controlled and features an automatic overdrive transaxle with an electronically controlled torque converter clutch.
Maybe some missed my point: Stockers don't need to run 4th gear overdrive.
