So this is the 4th time within about 2-3 years i have lost reverse in my trans in my 2001 dodge ram 1500 4x4 5.9L. it was just rebuilt 6 months ago and reverse went out yesterday. i dont do any hard wheeling at all. if i go offroad its to go down a dirt road or pull friends out and i might play once in a blue moon. Any ideas to eliminate reverse goin out? i.e. a stronger trans. help me out. im really tired of having to keep rebuilding transmissions

RE: No Reverse in 46re
a list of possibilities
NO REVERSE (D RANGES OK)
1. Gearshift Linkage/Cable Mis-adjusted/Damaged. 1. Repair or replace linkage parts as needed.
2. Park Sprag Sticking. 2. Replace overdrive annulus gear.
3. Rear Band Mis-adjusted/Worn. 3. Adjust band; replace.
4. Valve Body Malfunction. 4. Remove and service valve body. Replace valve body if any valves or valve bores are worn or damaged.
5. Rear Servo Malfunction. 5. Remove and disassemble transmission. Replace worn/damaged servo parts as necessary.
6. Direct Clutch in Overdrive Worn. 6. Disassemble overdrive. Replace worn or damaged parts.
7. Front Clutch Burnt. 7. Remove and disassemble transmission. Replace worn, damaged clutch parts as required.
drop the pan and try adjusting the rear band, some fluid, filter, and some of your time doesnt cost that much to try.
i do not abuse it at all. the guy said the past 3 times there is a piston that either gets cracked or turned sideways and it cuts the seal. i was going to put a new cooler in once i got it rebuilt by the same people (still under warranty. If it keeps breaking while its under warranty im just gonna keep getting it replaced for free. Once it isnt covered by warranty im going to look for a "bombproof" transmission. i plan to keep the truck and after the motor goes, a HEMI or a stroker motor will be put in.
I blew 5 transmissions on my GMC. First thing that would go out was the reverse, and it was because the converter went out. Dealer replaced them all.
Then after that, got the dodge and I read about the all the trans problems so I doubled up the cooler on the front, because the after-market coolers would not fit anwhere, installed a double deep dish pan and the temp guage with the sensor in the hot line. The installed the flex-a-fan electric fan, It made a big difference.
The factory fan doesn't cool the transmission right. If you run a factory fan it only turns on when the engine is hot ... not when the trans is hot. So if the engine is OK and the trans is hot you have no cooling.
So on the electric fan I put an extra temp sensor..on-off to turn on the electric fan when the trans gets to 190.
Of the 3 things, pan, cooler, fan, the fan made the biggest difference.
