Hi I am new to the site and was hoping that someone could help me out. I have a 2004 hemi ram 1500 with 105000 mi. the problem is that it will get locked in third gear and not shift up or down I can manualy shift it to second but it will not go into first at all. If i turn the key off and restart it it will shift fine for awhile then back to locked in third. Last fall I had the check engine light come on and took it to a dealer and 80 bucks later they told me the light was on because the transmission controller lost power but it was fine now and they had no ideal what happened. I figured i would get an opinion on the issue before i took it to the dealer again. thanks for any help

is it throwing any codes now?

 

^^^ agreed. You are going to have to go to an auto parts store and either let them pull the codes or find someone with an OBDII scanner and pull them. Please post your codes when you get them. Without the codes we can't tell you anything but broad and general information.

 

I stoped at a local shop this morning and the code was for a LR (low reverse) solenoid, sorry should have done that first was just anxious to get ideals. the scanner also said it could be a bad ground or the tcm. I downloaded the service manual and cannot find were this solenoid is located my guess would be by the valve body but I am still in the prosses of gatering information. thanks

 

If you post the actual code I can then post all the trouble shooting steps and diagnostics

 

P0750

 

it looks like I will have to replace the selonoid my question is will i have to do a quick learn for the tcm after the parts are changed? weedahoe I would still like the troubleshootin list just to be sure. thanks

 

HI...my name is roger i own an automatic transmission shop...
seems to me like your solenoid pack just went out...along the years they start to put in the dodge caravans,sebrings etc...basically passenger cars
up until 2003-2004 dodge ram change the transmission it used to be 518-618 in diesel engines...

i just need to know if its a 5 spd auto or 4spd...
there are 2 kinds of solenoid packs
black conector
white conector

to replace one of those ones you will have to take tha pan off and pull the valve body....transmission parts are around 250 for a new one and also updated

if im right when you turn the key off...gets out 1th gear when you go to a stop light boom...a limp mode...and other situations...

a good and used one can cost you 50 bucks...and relearn can be done by scanner or driving...

im positive if is not the 518 so you will have to replace the solenoid pack..
if is the 518 so your problem is not a solenoid...
theres no solenoid call low-Reverse for that one theres just 4 solenoids
wich are... lock up-o.d-pressure sensor-and gobernor pressure...

so if im right its gonna be the solenoid pack on either 5rf55e or 4rf55..i dont remember the name of that transmission....any more questions i might help go to daytonatransmissionservice.com and send me an email..
