79 Cruice air 727 shifter won't move
« on: July 09, 2019, 09:42 PM »
Sad to say my RV has spent more time as a lawn ornament and I'm getting ready to sell it.  Fired right up today but the shifter lever is stuck.  When I started it last fall it was very hard to get out of park but was able to do so.  Today I got it to neutral but couldn't get it moved back to park; luckily its on flat ground.  Is it just the cable that needs replacing or is it more serious?  The trans is original but was mated to a first gen Cummins diesel by the previous owner.

Hi, I did not like the gearshift on the dash as it was originally , So i replaced it with a Hurst Floor shifter Along side the R.S of the drivers seat Works fantastic ,   I don't know how hard it will be to find a cable , To check it (make sure the veh cant roll) Disconnect the cable from the trans and shift the trans lever thru all positions .

Thanks Frank!  Sorry for the delay.  So I did get the cable disconnected from the transmission but the level still won't move other than between neutral & drive.  I'm assuming it's the lever itself then?  That Hurst shifter looks nice, though I'm selling the RV and don't want to sink too much into it.  But I can't sell it as is so if so then so be it.

More likely the cable is frozen. You can get replacement cables from the aftermarket.

Hi Scott, I take it that by lever you mean the lever on the transmission .That is a very unlikely situation , I have never encountered it. You will have to drop the pan for further diagnosis . Let us know what you find  , Pictures are a great help  Frank   If you mean the shift lever on the dash , Then it probably is the cable .

My mistake, I meant the gear shift lever on the dash.  I'll replace the cable and see if that solves it.  I assume it's just a matter of finding one that's the right length?

The right length and the right ends. Having a brain fart here but there is a company out there that has them. Do a google search for shift cables.

By the way. When you get a new cable, make sure it's routed clear of the exhaust. That has killed many cables.
