Maybe this might help someone doing a search.
My transmission just started not shifting into D or R.  Restarting it allowed me to get from N into D.  After reading this old thread, I looked at things that might be allowing high idle speeds.  I found, both of the 2 return springs had broken off the throttle lever and were hanging by only their other fixed ends on the block.  Bending new ends, and reattaching seemed to have corrected my issue.

Gave it a try but it didn't do anything.  I'm willing to try anything at this point though.

I've been having an erratic issue with the Level System Alarm coming and going after the Kansas snowstorm and I'm starting to wonder if this has anything to do with possibly being a Shift Inhibitor function.  I pulled over and checked out all of the airbags and couldn't find any reason why the LSA lit up the first time and it certainly didn't cause the Allison to lock me out at that time and it went away.  The LSA alarm would come and go for seemingly no reason as I continued to drive for the next 8 hours or so and didn't stop my traveling but it has lit up recently and doesn't seem to be going away (as mentioned, I can't find any actual issues with the leveling system).  It hasn't lit up until this last time that I started the engine to keep the batteries up since the Powertech/Isuzu genet is such a drama queen when it gets cold. 

I guess I'll open up the controls for it and try to clean it all up this morning before I call in someone from the Allison repair shop 20 miles away.  For all the breakdown possibilities that I had considered before traveling, a transmission that won't shift out of neutral was not on the list. 

caflashbob, 
I disconnected everything and shut off the master disconnect switch while I was changing out the batteries for 30 minutes or so but the flashing 6 and R were right back when I started up the engine. 

Thank you all.
We have the same thing going on with our coach 1999 320 ,had new batteries installed and now cant get it to go in gear and light on the dash says level systems?

What's the engine RPM

Barbara. one or more of your slide pin lock sensors is not reporting that your pins are in place with the slides in and locked.  There is a brain box on the ceiling of the front basement bay.  In the lower corner of that box is a bypass switch.  Turn that switch to the other position and although the Level System light is still on, you can put the coach into gear.

An inspection of the locking pins with the slides in will find if a sensor is bad or a pin(s) are not in the lock position.  You do this with the slide bladder(s) still deflated (slide switch still on, yellow light on) and a ladder to see the top pins.

Engine rpm does not affect the level system light.

I don't know if this coach is new to you or not, but Rudy's comment reminds of a friend who, when he first bought his (used) coach, didn't hold the retract button/key long enough for the locking pins to do their job.  He stopped as soon as the slide stopped moving.  It needs just 2 or 3 seconds more for the pins to move.

Hi
I have had a similar problem with my coach ( 2000 featherlite vogue ) shifted from N to D or R  and the flash happens and at the time I used my tractor to push the coach back into the garage . The next day I tried the N to d again and same thing happened ( no go ) so I put the slide all the way out then back in . Then all worked as it should and because of covid 19 we have not used the coach as much as we normally would so it has sat for a while . I did go through the electrical drawings and found the one wire that comes from the HWH main slide / leveling control panel that goes to the Allison 4060 . But after a ton of hours on the computer to find out if I could disconnect the wire or put a dead man switch on it to temporary turn it off but do not want to mess anything up . From all the research I have found that on newer coaches there is no wire to the transmission from the slide so this does not happen . Again all is working ok now but because the coach is now 21 years old I would like to have a bypass just incase I can not find the problem when on the road far far away

any ideas

cat 3406e Allisson 4060 1 slide

thanks  dave

I have it all working now  8)
update

found the switch to bypass the flashing D and R for transmission , but in doing so disturbed the wiring that was in front of the switch , so I could not see it . all stopped working slide and air leveling not good . after lots of testing I found that the wire for the park brake connecter to be loose in the connecter and repaired it .  now everything works as it should and I have labeled inside the control box so this does not happen to anyone again . I wish I could find a schematic for the coach . I did find that the HWH system was made for Mitchel coach but could not find a wire schematic for the control box but Foretravel schematic looks close

thanks  dave

Contact FT they will send you them but you will need to pay for it.

I found a schematic on line from HWH and down loaded it that should help
