I have a 2001 Ram 1500 4x4 offroad with a 360/46re, and at WOT the truck will bounce off the rev limiter and not shift into 2nd until I let off of the throttle a little. All other upshifts are fine. Anyone have any ideas on this issue? From just looking at this site and others Iwill probably try to adjust the TV cable at the throttle body. I am new to Dodge (bought the truck used about 2 weeks ago) so any input would be greatly appreciated.

 

there is a pcm flash to correct that! look for dealer update tag on rad support if nonoe there have it flashed by dodge!

 

Any idea on cost for that?

 

I had this same problem and tried the TV cable adjustment. The onlyway the cable adjustment would work was if I adjusted it with too much slack causing it to shift terrible in every gear. I replaced my TB with a Fastman and the problem went away, it shifted right at 4800 in first gear. Now a week later its back to bouncing first off the rev limiter. Still trying to figure it out.

 

mine does that too. Throttle Valve adjustment doesnt correct it, it just helps it a tad.

 

Has anyone tried the PCM Flash fix? I cannot find a TSB about this specific issue, but have founda couple for other tranny issues.

Off the subject - xskylinedx, how do you like your K&N FIPK?

 

Your TPS is bad.

ill get flash number off my truck tomorrow it cost $69.00 @ dealer my truck under hard WOT starts would shift fine 1-2 3-4 then rev limit hit flash fixed it! update also dont allow lock up till 50 to 55mph

 

tazme695 - The flash number would be a tremendous help, Thanks!

dsertdog56 - wouldn't a bad TPS effect other components or show engine error codes?

 

The 46RE (Fig. 1) is a four speed fully automatic transmissions with an electronic governor. The 46RE is equipped with a lock-up clutch in the torque converter. First through third gear ranges are provided by the clutches, bands, overrunning clutch, and planetary gear sets in the transmission. Fourth gear range is provided by the overdrive unit that contains an overdrive clutch, direct clutch, planetary gear set, and overrunning clutch.
The transmission contains a front, rear, and direct clutch which function as the input driving components. It also contains the kickdown (front) and the low/reverse (rear) bands which, along with the overrunning clutch and overdrive clutch, serve as the holding components. The driving and holding components combine to select the necessary planetary gear components, in the front, rear, or overdrive planetary gear set, transfer the engine power from the input shaft through to the output shaft.
The valve body is mounted to the lower side of the transmission and contains the valves to control pressure regulation, fluid flow control, and clutch/band application. The oil pump is mounted at the front of the transmission and is driven by the torque converter hub. The pump supplies the oil pressure necessary for clutch/band actuation and transmission lubrication.

OPERATION
The application of each driving or holding component is controlled by the valve body based upon the manual lever position, throttle pressure, and governor pressure. The governor pressure is a variable pressure input to the valve body and is one of the signals that a shift is necessary. First through fourth gear are obtained by selectively applying and releasing the different clutches and bands. Engine power is thereby routed to the various planetary gear assemblies which combine with the overrunning clutch assemblies to generate the different gear ratios. The torque converter clutch is hydraulically applied and is released when fluid is vented from the hydraulic circuit by the torque converter control (TCC) solenoid on the valve body. The torque converter clutch is controlled by the Powertrain Control Module (PCM) . The torque converter clutch engages in fourth gear, and in third gear under various conditions, such as when the O/D switch is OFF, when the vehicle is cruising on a level surface after the vehicle has warmed up. The torque converter clutch will disengage momentarily when an increase in engine load is sensed by the PCM, such as when the vehicle begins to go uphill or the throttle pressure is increased. The torque converter clutch feature increases fuel economy and reduces the transmission fluid temperature.
Since the overdrive clutch is applied in fourth gear only and the direct clutch is applied in all ranges except fourth gear, the transmission operation for park, neutral, and first through third gear will be described first. Once these powerflows are described, the third to fourth shift sequence will be described.
