'05 2500 140 High Top
Hello all,
I'm having issues with my transmission and looking for help. Driving 2005 2500 SHC, 140 WB, 204,000 miles. Here is the order of events:
The shop did the following diagnostics after replacing the radiator:
I called the good Doktor A and he recommended that I mail him my TCM and he would test it in a working Sprinter. Then, he'd either reprogram mine or send me a used working one. At the very least, it would rule out the TCM. He's looking at it now, but based on the notes I provided, he's now thinking it's probably a transmission issue, not TCM.
Any insight or advice is greatly appreciated!!! I'm a full-timer (also work full-time out of this thing) and currently parked w/o a TCM in the Deschutes NF about 8 miles from Bend, OR.

I'm having issues with my transmission and looking for help. Driving 2005 2500 SHC, 140 WB, 204,000 miles. Here is the order of events:
Noticed crack in radiator expansion tank after low coolant light. On the way to the shop a week later to have the radiator replaced, the transmission wouldn't shift past 3rd or 4th gear (was stuck around 40 MPH), then went into limp mode.
Cycled the key and it reset, then tried driving in manual mode. This worked until 4th gear, then it got stuck. Cycling the key reset it again, but couldn't use manual mode. It was stuck in "D" and maxing out in 3rd or 4th gear. I think cycling the key at this point no longer reset it. Then CEL came on.
The shop did the following diagnostics after replacing the radiator:
Checked engine faults; P3323 in EGS control unit, gear comparison was negative several times.
Checked for faults in TCM, couldn't communicate with module.
R&R module checked for fluid intrusion, none present at the time.
Tested power and ground to module C1 Pin27 = 12.2V KDEO, C1 Pin30 1.8 ohms to ground - OK.
Corrected ATF fluid level and road tested; verified in limp mode.
After road test, tried scan tool again and could communicate with TCM normally.
Checked TCM faults; P2503 gear comparison was negative several times.
Checked TCM values and found control unit is recognizing P/R/N all normally, then faults out when vehicle is shifted into D.
The shop replaced the conductor plate and the transmission adapter plug, which was loose. Then did the following:Cleared faults and performed test drive. Vehicle still acting up after repairs.
No longer sets a fault right when the transmission is put into drive, but it did set a fault when shifting from 3rd - 4th gear.
It then went into limp model until the key was cycled and resets the computer.
They then suspected either a piston or valve in the valve body is not functioning properly (hydraulic issue).
They also suspected worn clutch packs (mechanical issue), possibly k3.
At this point, they referred me to a transmission specialist, who performed their own diagnostic. Here are his notes:
In limp mode. Will upshift out of 2nd gear. Scanned control modules and found 2232-001 in engine module. Found P2503 in EGS module Gear comparison was negative several times.
Fluid level and condition are both good; serviced recently.
Monitored transmission sensors via scan tool while road testing. Intermittently the EGS module loses communication. Before it loses communication, the readings for the input shaft and output shaft speed sensors go to zero. The upshift doesn't seem to be commanded. There may be an issue in the EGS module.
The transmission specialist suspected that I needed a new transmission control module and referred me to the only place in town who could do the programming -- the Chrysler dealership. They quoted $1500 for the TCM + 500 labor. No thank you.I called the good Doktor A and he recommended that I mail him my TCM and he would test it in a working Sprinter. Then, he'd either reprogram mine or send me a used working one. At the very least, it would rule out the TCM. He's looking at it now, but based on the notes I provided, he's now thinking it's probably a transmission issue, not TCM.
