Hello i have a 2000 dodge Ram and I tried to do a dual battery setup and turned it on started right up reved it to 3000 rpms let off and stalled started back up and had same results so I pulled the 2nd battery out and hooked everything back up as it was and was all good drove it home (30 miles) next morning get in it all is good drove for hour hour and a half then pull to red light take off and noticed I couldn't shift into 5th gear kept driving then 4th gear was delayed took it on the highway and I couldn't really feel it shift into 5th gear but rpms were about right maybe 100 or 200 above normal after about 20 minutes truck drops gear and od off light is illuminated and won't turn off get off highway Park and turned truck off after about 7 minutes od off light went away there was snow on the ground and I noticed a little bit of trans fluid on the ground checked level in neutral and was good so I go to get back on the highway and now no 4th gear get to the on ramp and don't feel 4th and 5th shift but again rpms were about right and after about 15 minutes od off comes back on get off highway turn off truck wait a little bit turn on to leave and now no 3rd gear keep driving home and then 2nd gear was now needing help to engage keep driving and now only way to get into 2nd is to shift manualy if I let the truck cool off get in and drive it will shift every gear but 5th when I come to a stop sign or red light and take off I only have first and second sometimes 3rd if I have to stop again I'm stuck in first unless I manually shift to second my truck would normally shift into 5th at 40mph reading about 1100 rpms so if I go 40 in 2nd let off gas put in neutral and back into drive it appears that I'm in 4th or 5th reading between 1400 and 1500 rpms I have not gotten a trans temp light only code I've ever gotten off my truck was a little while after my new trans was put in which came off of a tow truck I think it's a 47re but the code was p1740 which is the tcc or od solenoid I think, my trans was acting fine so I cleared the code and never had a problem for about 16000 miles until now so maybe I fried something with the dual battery and accidently put 24 volts through the truck I'm thinking the pcm maybe I don't think my truck has a tcm its part of the pcm or maybe shift solenoid or pressure solenoid or transmission control solenoid? Check valve? Blockage in flow somewhere? Trans fluid and filter was changed couple thousand miles ago with amsoil atf fluid since I have a lead foot haha also have amsoil signature series engine oil and amsoil severe gear rear diff fluid truck is 2wd the original trans went out at 126000 and truck now has 147000 I don't feel like this trans is trashed as the first trans was horrible when it went out no reverse no drive and if it did go into gear it would slip so bad I could barely move only symptom of going out was a loud whine it sounded like I had a supercharger my new trans will always go into drive/reverse 1st to 4th when completely cold doesn't whine can't feel or see any slippage so im thinking it's something more minor rather than a rebuild or replacement or is it about that time again any help would be greatly appreciated thank you

 

I've read this 5 times and still don't understand

must be the beer.

 

Your trans is overheating. Need to see if the check valve in the cooler line is clogged. Given your symptoms though, I suspect you may have toasted the trans.

 

I want to see a 47 tranny with 5th gear......

And I think it is possibly toasted as well. look at seleting check valve, drop pan and seee what is in there that shouldn't be there, and see if fluid smells burned. And depending on other issues, the fact that it only has 20,000 miles on it since rebuild is of no importnace and is not evidence of anything (other than it made it for 20,000 miles...)

 

5th gear is overdrive I'm 99 percent sure it's a 47re 4speed auto with overdrive it either came out of a v10 or a Cummins and the shop switched out bell housings so the trans would fit on my truck also my buddy has a 95 2500 12 valve Cummins also with a 47re with overdrive for a total of 5 gears anyways I changed the check valve it made a little difference but not to much the trans fluid is still cherry red although I did not drop the pan yet since I just changed fluid filter and gasket not to long ago I don't want to waste 140 dollars. I think that I hooked both or the battery's up wrong was running 24 volts through my truck at idle probably put it in drive to see if it would stall and fried something as I also said before I have not gotten any codes or trans temp light or have I smelt burning trans fluid

 

The bellhousing is a part of the transmission. You can't simply unbolt it, and bolt on a different one. it is all one big casting. If you don't see a weld line on your bellhousing, it's a 46RE. (or, if you have a V-10, or diesel, then you would have the 47/48RE.)

The 46-47-48 RE/RH are 4 speed autos with locking torque converter. Not five speeds. TCC lockup is that last 'shift' you feel. It isn't a discreet 'gear'.

PCM will disable O/D before the trans temp light comes on..... Keep driving, and it more than likely will come on.

Try cleaning the lines.... disconnect both lines at the trans, and run some solvent thru them, both directions. Make sure you get good flow. Flush them with trans fluid, and hook 'em back up. See if that doesn't help.

 

+1, and see if tranny fluid looks/smells burned. May need to drop the pan, (install a drain plug while you are there) and see waht may be lurking inside.

 

Well I just dropped the pan fluid looked ok I don't see any metal shavings but the magnet in the pan had the metallic goo on it not a lot though if I had to rate how bad it was from 1 being the worst to 10 being perfect I would give it a 8 1/2 it was not even close to my old trans when it burnt up i am curious to cut the filter open and see what's lurking inside there so for now I'm going to clean up put a new filter and the pan back on (I forgot to get the drain plug, would be really helpful but oh well) flush the cooler lines fill it back up and add a quarter to half a bottle of Lucas stop slip to make the amsoil atf just a tad bit thicker and maybe help with trans temp I know using Lucas in these trans is a bad idea but it's a last resort before rebuild but thank you guys for clearing things up for me on the trans types I was told it was a 47 but obviously not I was also told from the trans shop that they but a new torque converter in so im thinking if this doesn't work and nothing is plugged up then they lied and didn't put a new one in so sorry for sounding dumb transmissions are new to me I have plenty of experience with engines, suspension, exhaust and body work but never had to touch a trans besides fluid/filter changes

 

Transmissions are friggin black magic. You spin one side, and it comes out the other faster, slower, or the opposite direction...... what happens in between? Magic. Plain and simple.

Before putting chems in, I would check pressures, and see what gauges have to say. The additives are never a good plan, and will only make sure you will need a rebuild within a few months.....at best....

 

Yea that's true. So I ended up flushing the lines changed the filter flushed the cooler I had 3/4 of a quart of atf so I added just a little bit of the Lucas and shook it up all 4 gears shift still no lockup while driving I got a check engine light pulled the codes and got another p1740 and for first time p1756 both codes say same thing transmission manufacturer control so I ordered the od lockup solenoid and the control solenoid they will be in tomorrow morning I also took the truck for a drive when I got to work as that's where it's parked at still shifted all 4 gears put in neutral to check fluid and wasn't even reading on the stick. Btw when I flushed the trans cooler I got metal shavings out of it and when I cut open the filter there were some shavings in it so I'm thinking maybe when I burnt through my old trans all the crap got sucked into the cooler and they never flushed before new trans or the inside of the radiator/trans cooler is flaking I am thinking this because if there's not even enough fluid to show on the stick but it's shifting all 4 gears all the time just from a flush and filter replacement then maybe there's hope
