The most common AUTOMATIC TRANNY failures are on the RH line and the RE line (hydraulic & electronic). I have the 42re in my 1/2 ton 4x4.To no surprise, the governor pressure switch & solenoid went. BUT, WHEN I FIXED IT, I USED QUALITY PARTS. BORG WARNER IS A DODGE TRANNY'S BEST FRIEND. They make heavy duty parts that are proven to last. DO NOT BUY RED EAGLE!! The parts wear faster, and also the choice of most repair shops if they don't go with the local parts store's cheap parts. ALSO, USE THE RIGHT FLUID!!! DODGE TRANSMISSIONS RUN ON ATF 4, NOT ATF 3. Check with your mechanic before he does a fluid change. Most shops will put in ATF 3 and it WILL KILL YOUR TRANNY. Because of this, I lost the forward band also. I will be using the BORG WARNER kickdown band for this repair. From what I see, Castrol makes ATF 4 tranny fluid. Personally, I go to the dealership & ask for the MOPAR ATF 4 fluid. ATF 4 is comprised of more "vitamins & minerals" to keep your Dodge tranny healthy than ATF 3. Mopar themselves recommend ATF 4 for ALL AUTOMATIC DODGE TRUCKS. Whether you go Castrol or Mopar for your fluid, as long as its ATF 4, you'll be fine there. Also, change the fluid regularly. This is sorely forgotten. Change every 25,000-30,000 miles. Filter too.


I have the 46re transmission in my 4x4. The 6 represents the strength of the transmission. so naturally, the 42re/rh will be more fragile, most often found in 2wd 1/2 ton trucks and most Ram vans. Second, ALL DODGES REQUIRE ATF 4 FLUID UNLESS OTHERWISE STATED. Third, if you drop the oil pan, which should be done every 25000-30000 miles, and you see the magnet will metal shavings, THIS IS NORMAL. If you see snap rings, springs, and actual tranny parts in the pan, yeah, you got a problem. Definite rebuild. Also, if your tranny is just starting to slip, take it to a shop ASAP. Ask them to adjust the bands. Hopefully its just that. This needs to be done with EVERY fluid change. I say rebuild AND I recommend better parts while doing so. A little something I live by is this: Factory parts have factory problems. Dodge trannys will go through factory bands and governor solenoids in about 75,000-100,000 miles, depending on use. USE BETTER PARTS. Borg Warner HD parts are king in my book. A close second I've come to like is Raybestos, especially their Kevlar and Carbon Fiber bands. Kolene steels are perfect for any overhaul. Premium snap rings will prevent your reverse from going out (again). If you need to do a complete overhaul, its best you fix ALL the problems while you're in there. What I did ( cause I put 1200 miles on a broken transmission) is order from both Ebay and Cascade transmission parts. Here's my list: Kolene Steels, premium/high torque clutch plates, Raybestos Kevlar kickdown and reverse bands, premium band struts, all Borg Warner HD solenoids and sensors, Superior shift kit (watch the year when buying), I ran an upgraded Mopar lockup torque converter (not factory) and Felpro gaskets all the way around. Also used Mopar ATF 4 (cheaper version is Castrol ATF 4 or equivalent). But that's my case. Hopefully yours isn't as bad. But now that I've got a premium tranny, it hauls and races better than new


The 45RFE automatic transmission has identification numbers stamped above the oil pan gasket surface on driverside, and a bar code label containing additional information that may be useful.


The 42RE automatic transmission ID numbers are stamped onto the left side of the case, just above the oil pan gasket surface. The part number (1) build date (2) and serial numbers (3) are provided.


For manual trans. The NV4500 5-speed manual transmission-s ID nameplate (2) is fastened on the Power Take-off cover (1). The NV5600 6-speed manual transmission-s ID nameplate (1) consists of two tags. One tag is the transmission part number, the other is the manufacturer-s build date information. Both should be used when ordering replacement parts. The NV1500 5-speed manual transmission has two bar code tags located near the gear-shift lever housing. The tag on the right side contains the part number; the tag on the left side has the build sequence and date information.


Also if still original there is a sticker that if still present on drivers door (with door open look at it).
