Replying to: dustyk (Dec 16, 2008 7:20 am) I have a 2001 RT with 84k miles. It just started to have a problem getting into 2nd gear. Slow accel not as bad as hard accel where it revs really high and jumps, decel and it up shifts. Fluid level is good and clean. No other problems...Any suggestions before I take it to the shop?? Nick

Replying to: jt8man (Jan 03, 2009 9:51 am) Because of the age and miles and the time of year, here's my thoughts on possible causes in the order of probability: *Low fluid level. Make sure you check fluid level with the engine at full operating temperature, the vehicle on a flat, level surface, and the transmission in neutral. *Fluid level too high. Check for signs of bubbles (foaming) on the dipstick. *Transmission Throttle Position Lever sticking or binding, the throttle position lever return spring missing or broken, throttle linkage sticking/binding or out of adjustment. This is a very common problem on Mopars. *Low hydraulic pressure. This can be caused by a number of things, such as low fluid level, a partially clogged transmission filter or cooler lines, worn pump, a dirty or otherwise defective governor pressure valve, dirty/warped valve body, leaky internal seals or servos, etc. *Worn or slipping rear clutch, sticking rear clutch servo. I would recommend a Dodge technician check this out with a DRB3 scan tool first. There could be a defective Governor Pressure Sensor causing a false signal to the PCM. I'm not trying to make arbitrary conclusions here, but because you stated that even under light acceleration there is some flair, and the fact that this is an R/T, I am thinking this could be a rear clutch problem, especially if you've driven this vehicle hard and have not performed periodic transmission maintenance. However, 46REs are often thought to be in serious trouble when in fact the Throttle Position Lever is not working correctly, as noted above. For that matter, a lot of RE series problems are solved just be cleaning or replacing the valve body. A qualified and forthright Dodge technician is your best bet at this point, I think. Best regards, Dusty |

Replying to: jt8man (Jan 04, 2009 8:16 am) The Throttle Position Sensor is mounted to the left side of the throttlebody at a position in-plane to the end of the throttle shaft. There are three wires going to the sensor and two Torx screws are used to secure the sensor to the throttlebody that are easily removed. On 42 & 46RE transmissions, the Anti-drainback Valve is located in the transmission cooler outlet line near the radiator. On 545RFEs the anti-drainback valve is internal, however, Chrysler uses a small filter ahead of it to prevent the valve from becoming clogged. Best regards, Dusty

After reading all of the appends about automatic xmissions... I am very glad that I saved $872 and just orderd the manual xmission. Plus, the automatic xmission needs to have frequent fluid/filter changes just to keep it going. I never had one lick of trouble with manual xmission and it shifts just fine every time I push the lever to another position. The way I figure it... I got about a year of free fuel AND no xmission problems.

Grew up working on VWs Porches and lately GM. What I know of Son's Dodge got mostly from Internet so be gentle please. 1996 Dakota 3.9L 4WD LT235R15 tires on stock wheels. 75K miles. About 20% of the time on takeoff with more than the gentlest push on gas pedal, we get a very pronounced chatter, feels like a manual tranni clutch chatter or wheel hop. This will make your eyeballs dance. Backing off gas and the chatter stops. Have NOT tried to either floor it or leave gas down after chatter starts for fear of breaking something worse. Engine mounts seem OK in that revving in driveway, the engine moves maybe 1/4 inch. Shocks/springs seem OK as there in no lean and bouncing on the bumper gives one little bounce. I ran alongside the truck while Son drove looking for wheel hop, axle twist etc. Saw none, however, rear of transmission shook vertically about 1 inch, so replaced rear transmission mount. No effective change in the chatter. Seems to be a slight moan for about 2 seconds after chatter ends. Other than this, there are no issues with transmission operation at higher speeds or other gears. Previous owner is a friend, just drove to work and back, nothing exciting. All maintenance except tire changes was done at dealer. ATF looks/smells ok and is at the right level. Rubbing some between fingers feels more ‘grabbing’ than dexron/mercon, so that and dealer maintenance, I assume it is ATF+4. Planning on a drain and flush soon based on owners manual recommendations. Been reading past comments for last few weeks, saw nothing that seemed to fit, however any redirects to other posts will be gratefully accepted. Any/all comments and advice will be appreciated.

Replying to: dustyn (Jan 07, 2009 6:07 pm) Google also says: "DRAIN AND FILL PLUG LOCATIONS The NV3500 fill and drain plugs are both located in the front housing. The fill plug is at the passenger side of the housing. The drain plug is at the bottom of the housing. " Also found a pic at http://nv4500transmissions.com/parts-diagrams/case-assembly.htm The home page is http://nv4500transmissions.com/general-information/index.htm This site has a lot of info on both trannies. Note you want to put in transmission OIL not FLUID these are TOTALLY different animals. Note that you will likely have to pump the oil up to the fill hole. Good luck and happy hunting. vr Karl |

Replying to: dustyn (Jan 07, 2009 6:07 pm) I replaced the factory-fill with MTL after the 1st year of purchasing my Dakota new. The shifting was immeaditly better even when ambient temparture was well below 0F. As for your question about the fill plug.... as mentioned above, it should be pretty obvious on the side of the xmission case. There is nothing else there but metal. According to my factory shop manual, There were 2 manual xmissions used in Dakota (NV1500 and NV3500) The drain plug on BOTH of these is NOT a WRENCH. Instead it is an inverted drive. (sticks IN....not out!) The NV1500 used SQUARE drive and the NV3500 uses HEX drive. Just fill it up till fluid starts to ooze out of the fill hole. Approxamate capacities can be found on the internet. Just search for NV3500 and you will get 100s of hits. BTW: The NV3500 was also installed in 1000s of Chevrolet trucks too.
