Allison Transmission Questions

hi Allison Man

I have a 95 Monaco with a MD3060 w/touchpad. The thing that happens is every once in a while when trying to press into gear, a steady beep is audible and it just blinks without going into gear.

There was a power interuption once upon a time, (when the shutdown solenoid didnt shut the engine off but the electric did), but that has been fixed.

Is there a way to clear this issue and perhaps get the computer to reset on this? Or is this just a coincidence with the power issue and its a wire somewhere or something like that? I will check for codes tonight.

If we push enough buttons back and forth from N to D, N to R etc. eventually it will kick into gear and then run fine for quite a while. It only seems to do this once in a while. About every 6th start or so.

Any help is appreciated. Thanks Much!

--make it shift sooner when not pulling a load--will save gas-

Hi AllisonMan,

Our Church has a **** Eagle 10 bus with an Allison (maybe 740) tranny. The tranny oil cooler is a heat exchanger that uses the engine coolant to cool the tranny oil. This heat exchanger has rusted out and started to leak. Can you tell me where to get a replacement heat exchanger or if I can use a radiator-type cooler with or without a fan instead. Maybe a Hayden. Can you recomend specs on a radiator-type if that is acceptable. Dimensions, Fitting Size, BTU/Hr, Fan, etc.

Thanks for your time and expertise!

I have confirmed I've got a bad TPS (occasional lock out/reads 37% throttle). Can the new TPS be installed without use of a scanner to set idle percentage? 94 Gulfstream, Cummins turbo mechanical eng., Allison World 6 speed.

CPLATT41 and others: Are you noticing hard upshifts, too? Have the shift points changed? Finally, if you are getting an occassional "lock out" (if you have electronic shift panel, beeps and won't let you shift into gear) when starting out? Go to a shop with a good reputation and correct scanner for your transmission, have the throttle position sensor (TPS) values checked. That sensor can cause trouble and with the miles you have is a likely problem. They will check for other codes at that time, too. If that is OK take a look at the electrical connections on the wiring harness to the transmission, especially the large gang plug. Look for any oil leaks from that plug into the harness connector. A shop can check it quickly. Both have caused me trouble in the past. Good luck. Mike, 94 Gulfstream Sunstream DXL, cummins turbo diesel, Allison World Trans.

Allison Man, I've got a 2003 Winnebago Journey with a cat 3126E engine and allison 3000-mh trans. I am not getting any codes that there is an error, but the trans is shifting hard and seems underpowered at these times. The problem comes and goes erratically. It will jump from 1500 rpm to 2800 rpm then slam into the next gear. It also doesn't downshift at the right times. Any ideas.

HI, First I have to commend you for sharing your time and experience with others i'm sure you have helped save many a transmission proble with sharing your knowledge.
I just purchased a 94 Gulfstream with a 230 and 4060 transmission. This drove very nice for 600 miles and then strated to get a do not shift light if I hit a jolting bump on the high way. I reset with the down arrows and the the mode until tone but it still does the do not shift when hard bumps are hit and seems to be getting more sensituve to the bumps, also the cruse control droppped out a couple of time with the bumps.I live in KIngston WA. Have a nice day and God Bless america..Don

HI Allison Man,
I thinks it is awfully nice of you to share your experience with all us RVers. I just recently purchased a 34' Gulfstream with a 230hp Cummins and 4060 allison with md. It runs along nicely at 11800 at 63 mph. It has 66k miles on it and has been recently serviced. While on a 1600 mile trip it started giving a do not shift when a jarring bump is hit, it seems to be getting more sensitive to the bumps. I have reset with the arrow keys and puhed mode until tone. The cruise also has dropped out a couple of times when a hard jolt is hit. bridges are the worst. Tahnks for any in sight..Don Sr.
