Replying to: scoopyex (Mar 29, 2007 11:39 am) Scoop, You know, I had to go back to the my previous post and the originating one to figure what the heck you were talking about. Then I realized that I had experienced an exceptionally deep senior moment! Lack of sleep and a constant battle with insomnia are my only defense. My apologies. Scoopy is completely correct. The 545RFE family does not utilize a mechanical shift modulation control as the previous generation Mopar transmissions. In fact, any Chrysler-built automatic transmission that has includes "RFE" nomenclature relies soley on electronic control for shift schedules. To be specific, the fully electronic Mopar transmission's speed range selection is controlled by a number of direct and indirect inputs. Direct Inputs *Throttle Position Sensor *Crankshaft Position Sensor *Transmission Range Selector *Transmission Temperature Sensor *Input Shaft Speed Sensor *Output Shaft Speed Sensor *Line Pressure Sensors *Overdrive Switch Indirect Inputs Indirect inputs to the Transmission Control Module (TCM) are the result of Powertrain Control Module (PCM) outputs that represent various engine operating conditions (i.e. engine load). *engine/body/axle ratio *intake manifold pressure *target idle speed *torque reduction confirmation *engine coolant temperature *ambient air temperature *fuel temperature (some models) *air conditioning compressor enabled *battery temperature *charging voltage Best regards, Dusty

Replying to: bpeebles (Mar 31, 2007 1:17 pm) Not necessary. Besides, I'm not sure I could follow in your footsteps. By the way, my factory manual's starting to disintegrate, too. Bests, Dusty |

| i have a 1999 dakota r/t reg cab. there is nothing wrong with it besides i'd love to have a 5-speed tranny in it. i know that it has the 46re tranny in it which is the full size truck trans, so that should mean that the full size manual should fit in it but i don't know the name on the tranny or for sure if it would fit. if anyone could tell me anything, i'd appreciate it. thanks | |

Replying to: mopar360rt (Apr 02, 2007 7:39 pm) If you are suggesting that you want to install one of the newer automotic xmissions, be prepared to also reprogram the engine-computer -to- transmission computer communications. Modern automatic xmissions do most of their "thinking" insiside a computer to determine shift-points and other important stuff. In model-year 2000, the Dakota recieved a the Jeep 4.7L V8 which came with a new automatic xmission. Personally, I orderd mine V8 from the factory with the 5-speed manual and enjoy up to 21MPG with it. |
