Try to get a later year model with the 66RFE (68RE gear sets) than the 545RFE. The 66RFE is a legit 6 speed, even if the ratios are poor compared to a modern GM / Ford 6 spd. 4.10s are a must, as the tranny has a very tall 6th.
The 545RFE was a 4 speed with a 5th gear programmed in, that later received a "marketing 6th gear", which became the 65RFE. Thank God that never made it into the HD trucks.
