i have a 05 with the 48re it has had a 1-2-1-2 shuttle shift problum.i have replaced the gov press solenoid and the transducer.and have taken it to the dealer for a computor flash.it help it but didnt fix it. all the way.so my question is. can i buy a transmission controller and over ride this problum..such as setting my own 1-2 shift points.if so please give me the names of who offers them..thanks ray or can it just be a bad gov press sol.it wasnt bought from a dodge dealer..it was bought from a after market dealer from Fl. ???????

 

Yes sir DTT, ATS, and Suncoast all make one.

 

Maybe, maybe not. Depends on what the source of the shuttle shift is, electronic or mechanical. A DTT Shift Enhancer will help if it is just an electrical malf and you want the TV pressure to advance further.

If its a mechanical issue all the boxes in the world will not help, the trans will have to be at least partly disassembled. Most of the mechanical issues revolve around the valve body and the front accumulator. These can all be addressed without pulling the trans. Since the gov solenoid and transducer did not help I would suspect you need some other work to totally fix the issue.

Just how bad is the shuttle? At what throttle position does happen/not happen?


I am not aware the ATS or Suncoast offer a product just for the shuttle shift but they could have. From experience I KNOW the DTT piece works IF it is electrcal.

 

hello,thanks for the help..it's not as bad when you first start.meaning the fluid is still cool.it shifts almost normal.after it warms up.i can really baby it and it wont do it.when it does down shift after shifting into 2nd and then goes back into 1st i just hold it steady at 2750 to 2800rpm and it will shift on out.if i let out of it after it 1-2-1 and let it shift it usually slows down to much and it goes back into 1st and so on.i am thinking i may have gotten a bad press solenoid.the truck only has 84000 miles and never has had a hitch in it.Ooh and if i drive it a little hard on take off. it will shift great..hard and firm..but thats not how i like to drive L.O.L. but it wil shift fine when i do this style of driving.

 

Your getting a downshift to first at 2700-2800 rpms?

Does using TH have any effect on the shuttle shift?

 

update....i have noticed that if i drive it more agressive.it shifts fine..and it's not really shifting back down at 2700-2800 rpm you just have to hold it steady at 2700 to 2800 to get it to shift on out to 2nd

 

My truck has recently started shifting the same way. I have replaced the governor pressure solenoid and sensor and it still does the same thing. I will try adjusting the bands because it does hold the gears too long before shifting.

 

that is the only thing i havent tried.and i was thinking i may have a bad gov press sol..even thou i have replaced it..

 

Woo Hoooooooooo major break thru !!!!!!!!!! adjusted the 1-2 band and IT ***** LIKE BUTTER.ALL FIXED !!!!!!!!!!!!

 

Yeah I adjusted both front and rear and it shifts perfect now.
