Suncoast tranny major issues

[Amfw119]

Ok I can't find a lot of useful info on any of this any help appreciated



Transmission giving me all sorts of fits. Earlier it was throwing code p0730 and would rev up before basically slamming into gear. Now I just went to store and had to back out on a slight hill and it wouldn't go anywhere reved up really high and eventually slammed into gear incredibly hard kind of roasted tires and some not so good sound either hope I didn't break anything outside tranny but codes are in addition to p0730 are now
P0715
P0720
P0791 and actually no p0730 now oddly enough. And tow haul flashes
Desperate need of guidance here thanks a lot!!!!!

sounds to me like its shot! seen this happen with a few suncoast units

[Amfw119]

Oh no that's no good. I've been told it could possibly b pressure control solenoid? Any chance that's what it is? Thanks for the reply!

[rdunagan]

possible but with it slammin gears like it is and the reverse thing dont get your hopes up.

I have seen many Suncoasts toasted. I hate to break it to you but it sounds like yours is too.

Appreciate everyones reply and now new developments. Truck has same codes but now after starting the truck and taking off after putting truck into gear(which seems to me that linkage is really tight now) anyways from park it does start out in first but it seems to clang into other gears maybe only shifting once or twice ending up in fourth gear and remaining there even if I stop and take back off it remains in fourth gear. No matter my speed truck says in fourth he's until I put back into park. I will pull pan off and see if I've got anything in fluid. Any additional information on this?

its gone. brothers is doing the same thing and his is stock. like said above we have seen alot of suncoast go out. they arent as bulletproof as they say they are

[Amfw119]

Alright I was afraid of that just holding out hope lol. Thanks a lot.

Depending on how long you have had it, they may warranty it. You'll probably be out labor but if you have a tranny jack and a couple of good buddies, it can be tackled in about 6 hours. But yeah, it has probably chunked several of the internals, slamming into gear will trash one in a hurry.

strong guys usually help also lol. that transfer case isnt the lightest thing in the world for us guys that arent strong like me
