2001 CTD auto tranny problem
From : bill allemann
Q: i have a 2001 ram 2500 with ctd and i believe the 46re tranny. 160k mileage. recently the tranny has started doing tricks somewhat consistently in colder weather. after driving just a little a few blocks if i go to reverse and back to forward like to turn around in a tight place the tranny seems to let go pretty much like being in neutral. going to r and back to d doesnt usually do anything. after maybe 5 seconds at idle there is the usual mild jolt like when you first select drive and off you go normally. the severity of this varies somewhat possibly with ambient temperature and i dont think it has happened when the truck is completely warmed up. at first i thought it had to do with the slope of the ground where the truck was parked but now im not too sure about that. is this likely to be the computer gadget and if so is dealing with that an external process ill be taking it to a shop but i first wanted to get a feel for whats going on. thanks bill .

in a 2001 cummins truck you have a 47re. you should be able to get trouble codes by doing a key on/off three times then leaving it on and watching the odo for the p**** codes. also you dont mention if the bands have been adjusted. if not do so since 160k is way after the maintenance interval. after reading again you dont mention fluid level. sounds stupid but it is sometimes overlooked. also converter drainback can be a problem. try starting the engine in neutral and allowing a minute or so of idle time then putting it in gear. if this eliminates the problem youve also found the simplest solution. if you get codes itll probably have to do with the governor solenoids or the apps. -- max join www.devilbrad.com and find out what free exchange of info is all about. there are four boxes to be used in defense of liberty soap ballot jury and ammo. please use in that order. -ed howdershelt author i have a 2001 ram 2500 with ctd and i believe the 46re tranny. 160k mileage. recently the tranny has started doing tricks somewhat consistently in colder weather. after driving just a little a few blocks if i go to reverse and back to forward like to turn around in a tight place the tranny seems to let go pretty much like being in neutral. going to r and back to d doesnt usually do anything. after maybe 5 seconds at idle there is the usual mild jolt like when you first select drive and off you go normally. the severity of this varies somewhat possibly with ambient temperature and i dont think it has happened when the truck is completely warmed up. at first i thought it had to do with the slope of the ground where the truck was parked but now im not too sure about that. is this likely to be the computer gadget and if so is dealing with that an external process ill be taking it to a shop but i first wanted to get a feel for whats going on. thanks bill .

youre making an assumption that is clearly wrong. once again miles that would be you. you are under the assumption that the entire spring is defective and that is not always the case. my company produces whats called load cells or force transducers which rely on the very predictable bending properties of metal. yes and if that is true iirc you also claim to work primarily in the aircraft industry where the aluminum alloys used there have very different properties than spring steel. the companies that rebuild springs are one industry that uses them. look it up. yes i do know far more than you in this area. really exactly what do they use them for on automotive springs -- if at first you dont succeed youre not cut out for skydiving .

fluid and filter change cant hurt. but im also thinking rebuild time. seems like every dodge vehicle ive owned has needed a rebuild some time in the time ive owned it. my 1974 dodge dart i had a fluid change and band adjustment at the local repair garage. went from working fine to definitely wrong. so skip the band adjustment as part of routine maint. fluid and filter and gasket change is a good idea. that transmission fluid sure gets thick and heavy. -- christopher a. young you cant shout down a troll. you have to starve them. .. sounds like $2000 of rebuild to me bill allemann custom4173@sbcglobal.netinvalid wrote in message i have a 2001 ram 2500 with ctd and i believe the 46re tranny. 160k mileage. recently the tranny has started doing tricks somewhat consistently in colder weather. after driving just a little a few blocks if i go to reverse and back to forward like to turn around in a tight place the tranny seems to let go pretty much like being in neutral. going to r and back to d doesnt usually do anything. after maybe 5 seconds at idle there is the usual mild jolt like when you first select drive and off you go normally. the severity of this varies somewhat possibly with ambient temperature and i dont think it has happened when the truck is completely warmed up. at first i thought it had to do with the slope of the ground where the truck was parked but now im not too sure about that. is this likely to be the computer gadget and if so is dealing with that an external process ill be taking it to a shop but i first wanted to get a feel for whats going on. thanks bill .

if the bands are properly adjusted it wont do anything negative to trans operation. if the fluid was thick and heavy and you had it changed its very possible the new fluid unclogged some internal leaks by sweaping away the dirt. atf has a high detergent content compared to motor oil. also atf is about 10w compared to a multiviscosity motor oil. about the only thing that indicates tearing the trans down is the rear drum seal leak as kunkle noted. while this is a possibility much diagnostic has to occur between now and final determination of that as the problem. it would be a bad thing to spend $2500 on a rebuild only to find that the problem was far simpler. -- max join www.devilbrad.com and find out what free exchange of info is all about. there are four boxes to be used in defense of liberty soap ballot jury and ammo. please use in that order. -ed howdershelt author fluid and filter change cant hurt. but im also thinking rebuild time. seems like every dodge vehicle ive owned has needed a rebuild some time in the time ive owned it. my 1974 dodge dart i had a fluid change and band adjustment at the local repair garage. went from working fine to definitely wrong. so skip the band adjustment as part of routine maint. fluid and filter and gasket change is a good idea. that transmission fluid sure gets thick and heavy. -- christopher a. young you cant shout down a troll. you have to starve them. . sounds like $2000 of rebuild to me bill allemann custom4173@sbcglobal.netinvalid wrote in message i have a 2001 ram 2500 with ctd and i believe the 46re tranny. 160k mileage. recently the tranny has started doing tricks somewhat consistently in colder weather. after driving just a little a few blocks if i go to reverse and back to forward like to turn around in a tight place the tranny seems to let go pretty much like being in neutral. going to r and back to d doesnt usually do anything. after maybe 5 seconds at idle there is the usual mild jolt like when you first select drive and off you go normally. the severity of this varies somewhat possibly with ambient temperature and i dont think it has happened when the truck is completely warmed up. at first i thought it had to do with the slope of the ground where the truck was parked but now im not too sure about that. is this likely to be the computer gadget and if so is dealing with that an external process ill be taking it to a shop but i first wanted to get a feel for whats going on. thanks bill .

bands were adjusted fluid filter changed about 4k miles back. bill at this point i would try an additive like trans-x or lucas; it doesnt cost much and might rejuvenate the seals enough to squeeze a few more miles from the unit. failure to drive forward in d when cold could be hardened/shrunken seals in the rear clutch. this allows enough leakage to prevent clutch engagement but the seals soften somewhat when the fluid warms up and will seal better. a clogged filter could cause the same problem. if the problem occurs after a few blocks of driving converter drainback isnt likely the problem and no bands are used to start out in d so band adjustment while probably overdue isnt the problem either. .

i would like to let everyone in the group know many of you probably already do know though that you must use atf +3 or +4 in dodge vehicles. i had one tranny go in a 1997 dakota just two weeks after i bought it had only 65k miles. luckily the warranty company guardian was very good at following through with their warranty claims to repair it. they actually replaced it with a used one with close to same mileage on it. but of course the freaking transmission shop put mercon dexron iii in it after replacing it. i have been meaning to change it to atf type but just recently got around to getting er done. just prior to changing the fluid with cold temperatures up here in new jersey i noticed it was slipping a bit when taking off from a stop until it warmed up a bit. after replacing the fluid to atf +4 this has no longer happened and i could tell the difference in smoothness of shifting immediately. barry guidry new jersey i have a 2001 ram 2500 with ctd and i believe the 46re tranny. 160k mileage. recently the tranny has started doing tricks somewhat consistently in colder weather. after driving just a little a few blocks if i go to reverse and back to forward like to turn around in a tight place the tranny seems to let go pretty much like being in neutral. going to r and back to d doesnt usually do anything. after maybe 5 seconds at idle there is the usual mild jolt like when you first select drive and off you go normally. the severity of this varies somewhat possibly with ambient temperature and i dont think it has happened when the truck is completely warmed up. at first i thought it had to do with the slope of the ground where the truck was parked but now im not too sure about that. is this likely to be the computer gadget and if so is dealing with that an external process ill be taking it to a shop but i first wanted to get a feel for whats going on. thanks bill .
