Technical Support / Misc SMC & Safari Wiring Diagrams
« Last post by Steve Huber Co-Admin on July 20, 2019, 07:28:28 PM »
I just loaded a number of SMC and Safari wiring diagrams with drawing dates from 1994 to 2017. Since most SMC and Monaco coaches are wired similarly and the mfgr often makes only slight modifications between model years, these may be of assistance. They are located at the end of the Coach Assist Library list. Thanks to Mike Shumack for supplying them.

Suggest you check the level on the dipstick when tranny is warm before adding any more fluid.

I read the same thing in the Allison manual.  However, I'm still confused by the low oil indication not changing after I added 4 quarts of TranSynd.  Is 4 quarts low as low as the message will indicate?  The manual doesn't say.  Do I need to add more?  How much?

From a Google search:

"Allison 3000 transmissions can hold approximately 29 quarts of fluid; the larger Allison 4000 can hold approximately 48 quarts. But not all of this fluid is in the transmission pan. Much is contained in the transmission cooler, cooler lines, and torque converter. Therefore, an Allison 3000 could require only 19 quarts on a refill (rather than 29 quarts when changing fluids), and an Allison 4000 could require only 39 quarts on a refill (instead of 48 quarts when changing fluids). If filters only are changed, these numbers drop markedly. Only two quarts are lost when changing the main filter. Eight quarts are lost when changing the lube filter."

I need help interpreting Allison fluid codes on the control panel.  I took my 2006 Monterey with an Allison MH4000 transmission to  a local heavy duty truck service repair shop for service.  They changed the filters and refilled the transmission fluid with 2 gallons of TranSynd that I supplied.  The service guy indicated that after doing the filter replacement they put in the 2 gallons and the dip stick indicated the fluid was up to proper level.  I drove it around 10 miles to my home and checked the level on the control panel.  It indicated I was 4 quarts low (oLLo4).  So I put in 4 quarts and drove it a couple of miles and got the temp up to the required 140 F.  I rechecked it and it still indicates its 4 quarts low.  Same oLLo4 code.  So, I am confused on how to proceed.  Is it still 4 quarts low?  Do I need to add more TranSynd?  Leaving on a long trip in a couple of weeks and want to make sure I have this up to proper level.
Thanks for your help.
A couple of comments.  First, our local Colorado certified Allison service shop, TransWest, would not do the service.  They will not work on motorhomes over 10 years old.  Second, I went on the Allison website to get their help and they wanted to charge me $5 to answer my question.

On my '04 Monterey the lights came on because the wheel sensor was unplugged.  It was unplugged because Beaver had wrapped the excess lead wire around the axle to take out (or store) slack.  Going over a big dip caused the suspension to extend which caused the wire to disconnect from the wheel sensor.  One less wrap around the axle fixed it.

On my 2005, the ABS "valve' assembly is on the frame cross member just fwd of the drive axle. I have not seen the ABS controller.
I try to photo document all the parts on my coach (sometimes to identify what they are).

I think my ABS controller is mounted near the ABS Valves (In need to crawl back under the coach to verify). I seem to recall seeing the "frame mounted" unit near the ABS valve assembly and recall noticing the wiring that goes into the bottom of the controller not having any "weather protection'". But I can't find any photo of this in my files.

If I can get back under the coach this weekend, I'll try to locate the controller and get some photos (but this still may not help you as I have a '05 Patriot and you have a '06 Monterey).
Good luck

When I contacted REV Recreation group to get part number for my ABS control unit on my 2006 Monterey they said I have a premium cab mounted unit. Previously someone posted about a frame mounted unit on a 2005 Beaver. Does anyone know where to look on my coach for a cab mounted control unit?

As always and help is greatly appreciated.
Thank you Paul!
