Not Shifting into OD ( 48re )

[Ed's5.9]

Hello, I'll try to keep this short and to the point. I own a 04 Ram 2500, SBQC, 5.9L 24v, 4x4 Automatic with 250k+mi. on it , Sunday morning I went on a drive and noticed that the transmission was not shifting into over drive, all the other gears seem to work fine though. I checked the fluid level and it was at proper level it also looked clean as well. I had a friend hook up a scanner to it and check for any silent DTC's and got nothing. He then checked APPS readings because I changed it 2 weeks ago and he advised that I calibrated the new APPS within the required tolerances so it was not that. We then took the truck for a drive while he read the scanner and he said that all was operating normally from the ECM side, OD command was being sent to the transmission but the transmission was not responding to the command, I drove the truck up to 60mph and TCC would lock up as well but no OD. I have never had to deal with a faulty auto transmission so I have been doing some research to see what might cause this. What I have found is that it may be one of or a combination of the following, pressure transducer, pressure solenoid, TCC/OD solenoid group or the TCC/OD group wire harness. I just wanted to run it buy the 48re gurus here and see if there is anything I might be overlooking also if there is a proper way to diagnose the items I listed without dropping the oil pan.  Based on the write-ups I have seen changing the parts that I listed is pretty straight forward so I feel I can do it myself if there are no other possible culprits. Thank you all for your time.

I would change governor pressure sensor, geveenor pressure solenoid, and od solenoid. While you are in there adjust both bands and change the filter. I also add a qt of lucas trans fix to help coat the bands. Im not a transmission expert but the first two parts fix a lot of weird problems but I would chang the od solenoid just to be safe

Did all of the above over the weekend, the transmission showed improvement but it is on its last leg. It now shifts into OD but it is shifting late (55-58mph)  and when it tries to lock up after OD (almost at 60mph) it starts to slip really bad. After thinking it over I am just going to have to save up and have a transmission built to better suit the truck, with the current mods that I have I should be able to get 500whp with a proper tune but I haven't done so because of the transmission and the bullydog's tuning limitations. Stay tuned as I will be posting up some parts for sale in classified section to help fund the new trans. Thank you !

thank you for the refferal, since I dont have all the money yet I have a decent amount of time to do some research. I wanted to see if I could find someone locally to build me a tranny to avoid all the Freight charges and hassle with the core but down here in South FL. there arent too many reputable transmission builders so we will see how it turns out.

Hey Ed,  I know of a very reputable transmission shop in Brooksville, Fl. I use them and they are an awesome Family owned  business of 35 years!! They rebuilt the transmission on my 91 Lincoln and did the inspection,fluid change and tail shaft install on YabbaDoo when I first bought the truck. They are a very honest and trustworthy shop with top notch technicians!! I know it would be a bit of a drive for you but, for me it is worth the drive up to Brooksville Transmissions from Tampa to know you are dealing with an awesome honest and trustworthy shop  They have awesome customer service and fair pricing with a nationwide warranty   http://brooksvilletransmissions.net

Thanks Tracy, I checked out a few options and ended up narrowing things down to 2 guys that I have done business with before Richard from Florida Performance Diesel or Ashley over at Black's Diesel Performance. The engine I have in the truck now is a reman by Ashley at Black's and they did a great job with it as for Richard he helped me source parts and do the swap when I got the engine from Ashley. I will be posting the quotes shortly to compare transmissions and prices with you guys .

input please

I know that Goerend converters are great. If you are not going completely wild for power, you can use the stock transmission with an upgraded VB and converter. You may also want to think about upgrading the input shaft. I am at 365 HP to the ground and I can't make my 47RE slip but I did break the center out of the front drum.

I am definately going with a billet input shaft, my goal is to hit 500hp.

Good. It is not a good feeling to be 600 miles from home towing my fiver and hear that "BANG"........ Although it seems like no tranny shop I talked to ever heard of the drum breaking. They all said it was common to strip the splines.

[Ed's5.9]

Anyone here ever use the PRW flexplates ? I dont think I really need a fancy billet Flex plate since I'll never be boost launching the truck or will be taking it to the track. Here is a link https://www.rebelperformance.com/prw-1835910-dodge-5-9l-88-up-sfi-152t-steel-flexplate-int-bal.html

hey, when you got skills you got skills !! That really sucks though not only breaking down but doing so 600 mi from home and towing ... I'm sure it costed you twice as much to get you out of that jam than what it would have cost to go billet when you had the chance.

[MnTom]

Goerends has stock and billet flex plates, but they are a little more expensive than the PRW. http://www.goerend.com/index.cfm?Page_name=dodge%20diesel%20parts

How does a flex plate get "Designed to maximize the valvetrain efficiency of your Dodge Cummins engine"?

Has anyone here had any work done by inline performance out of Bushnell, Florida ?
