As an update - The solenoid was replaced, as was a new internal filter replaced (There is a suction side filter housing available from Allison). This is an internal filter in addition to the two external filters. Getting the control valve body back in place is a real bear, no two ways about...

Thanks Ronmar, Super helpful. From what I can tell 29507453 which cross references to 5945-01-360-5161 which when searching Allison parts also returns 29537371 so based on this knowledge I believe that 29537371 supercedes 29507453. I appreciate the haelp, and will go to my best Allison dealer...

Thanks Suprman, You have been an incredible help to me over the years, from packaging a transfer case and sending to Reno, and even some phone support at times. Your knowledge is epic. For the life of me, I can't find the exploded diagrams or any reference to the transmission solenoid part...

Hello, I have visually identified and found resistance issues with Solenoid D and E in the transmission of a 2002 A1 M1078 with the WTECIII 3070sp. Where would one find the part numbers for the solenoids? I read the numbers off of them, and they have a top number of 7371 / does that map to...

sooooooo… we opened up a clean valve body, and solenoid D was half unplugged, and E which was the coded short to ground looks like some degraded material. Stranger yet was a 3 inch long 1/2” stick wedged in a corner. No metal shavings and the fluid and filters spotless. I had flushed to...

Thank you! Will review

Hello, 2002 LMTV - M1078 A1 WTEC III After dealing with transmission codes, we have tested the harness, Trans ECM, and all values to find the cause of 44-16 which is a short to ground of the "E" Solenoid. I have been told it is usually wiring, but after a month of testing, we can;t identify...

sorry, forgot it is WTEC III

It's a 2002 A1. I got my son to help me and we tested all solenoids, and this time realizing there are upper case and lower case letters on P119 we measured correct ohms on all solenoids within range. We then did jumper the correct pins on J119 and measured continuity as expected for E...

I may have spoken too soon. After test drive it reverted to 4th gear mode, and when parked and restarted resumed the DNS status. I undid the J119/P119 cab harness connector and OHM'd out the various pins per manual. My code was D1 4416, which is E solenoid, and when testing that solenoid I...

Just a note of what solved my trans codes 6 months ago had to get towed home for Allison Transmission codes: D1 4416 D2 4621 D3 4627 It started with limiting to gear 5 from 7 and very hard shifting from 2nd to 3rd. After clearing and much consternation on a trip, I got it towed as when shiut...

I spoke to CW and he was back on the road, was an issue with K11 relay starter engagement.

Hi, just saw this. I live in Reno and have a spare, but am out of town until Friday. Please call tomorrow, and I’ll see if I can help. 775-815-9226

Hi everyone, new to me M1078 member based in Reno NV. Bought the M1078 from Eric Hines of BuiltMFG. One item still seeking is a tan tailgate if anyone wants to sell or trade for a second 55gal fuel tank as I have a spare. Nice to meet everyone! Josh 2002 M1078 A1, Reno NV

I took the opposite route and added the 1083 bed to my 1078 - it worked great, and for what I need was great alternative.
