Trans Locked Up

[andy-stevenson]

Just wondering if anybody has experienced or heard of a transmission locking/seizing up while driving? Atleast I think it was the transmission..

Driving down the highway doing 70 this morning and ssomething locked up for a second, just enough to throw me forward and chirp the tires. Then it drove again fine and then again something locked up and threw me forward and chirped the tires.

Not sure if this is the trans? Torque converter? T case? Rear end? Anybody hear of anything like this?

Check the t case fluid and see what color it is...

I have a complete working trans you can use if needed Andy.sucks when these unexpected things happen.let.me know if I can help.

Had something like that happen once in another truck. Bolt came out of the carrier in the rear diff and it would get caught between the carrier and the case.

It made some great sounds too

I had the same thing happen to me and it ended up being a snap ring in the transfer case that broke. It ended up taking out the speed sensor and locked up my trans for a second. My first sign was while backing up if i throttled it I'd get a huge bang. Hope this helps!

Sounds like transfer case.

Well whatever it is. It shit the bed this morning...truck just revs no power to the wheels. Rattles like a son of a bitch from the bellhousing. But what's confusing me is the truck started smoking at the exact same time? Nice bluish haze

Truck has reverse, but when you put it into drive nothing, it rolls forward at first when it first engages but then nothing.

does it say range shift inhibited or no

 

[andy-stevenson]

Yes

 

[onebaddmaxxx]

i see you have a built trans, but I have seen some stock trans burn the c1s up cause the same thing where you have reverse and as soon as you go to drive it throws range shift inhibited. have you dropped the pan to check for material or pulled the spin on down to look at the magnet?

 

[andy-stevenson]

I haven't yet. It literally just happened.

 

[andy-stevenson]

Definitely sounds like it's coming from the transmission vs transfer case. Only code is p0872

 

[onebaddmaxxx]

probably a Stuck E shift valve. Need yourself the sizing tool. Pull the vb down and see if its stuck. Good time to put mikes trim and shift springs in

 

[andy-stevenson]

I've had the p0872 before but it's never not let the truck drive.

It's weird, start up the truck and there's a bit of grinding then it goes away. Once the Trans warms up a bit the grinding starts again only in park or neutral. When I turn the truck off you can still hear the grinding slowing down as the transmission stops spinning.

In park I can clear the codes, reverse works like normal. Drop it down to drive and take your foot off the brake and the truck will roll forward until it throws the p0872 then it goes into 4th and nothing. But like I've said before when the truck has thrown a p0872 it goes into 4th but will still drive.

Can put the truck into reverse after the p0872 and it's still fine.

 

[onebaddmaxxx]

Yeah. Usually in my experience with the p0872, it will start in drive and about the time you get moving, it will clunk and make a bunch of scary noises.

Mine did the same thing, had reverse and no drive, c1's were gone. I got a 07 something and it never came back nor did the truck move. It made no noises though.

 

[andy-stevenson]

Sounds like I'll see some burnt up c1s when I pull it then. Will post up pics.

Well i would definately pull the VB down, and try to check to e-shift valve. That doesnt cost anything...

The E shift valve doesn't stick by itself unless it's a fresh trans.
