2001 ram 1500 5.9 4speed auto bad !!!!

kmzues · 04-02-2009, 07:29 PM

At 120000 miles i was driving the interstate and overdrive kicked out , a few miles later trans temp lite went on. i imediatly pulled over and shut down the truck for 30 minites. i noticed fluid leaking from the front of the trans . after cooling down drove slowly home , while driving i put the trans into neutral when i could to keep fluid moving but not using trans. my shop guy flushed out trans and removed check valve. truck worked fine for about 500 miles no leaks . then while driving 3rd gear went out , all i had was 1st and reverse ! no trans temp lite ! while limping home i would occasionally go into 3rd them i would lose it again !
so i changed the filter and fluid (atf+4) and took it for a test drive . it shifted fine for about 2 miles , then 3rd was gone again ! just 1st and reverse. i checked the cooling lines both were cold ! when i changed the fluid i blow out the lines till no trans fluid came out . i also tried to blow compressed air into the line conection on the trans the top connection would accept air to a point then blow fluid back out . the lower would not take any air , like there was a one way valve ? is the trans toast or should i check something else ? i also have a p1740 code coming up .

thanks for your help !!

Tee into a transmission cooler line with a pressure gauge. Actuate lock up with the DRBIII®. Pressure should go up 5 to 10 PSI when lock up is requested. If it does look at possible problems with the torque converter, front pump, input shaft and seal rings. If pressure does not go up look at the transmission solenoids.
i no you may not have acces to a DRBIII sounds like an electrical issue in the valve body or the TC ... ? I do not think the tranny is junk yet because you have the 5.9L comes with a beefer transsmission but i would take care of it right away if its the solonoid it cost only 95 bucks and is easy acces..
