Did you check the rear yet?

Arisley · Dec 29, 2014

Sounds like the shifter pin. Or something else in the shifter.

ju015dd · Dec 29, 2014

Shifter pin is in its place. Don't think it is rear end cause truck will move when i leave shifter in neutral position. When in what is suppose to be second the shifter bounces back and forth.

ju015dd · Dec 29, 2014

When sitting in truck with it off. I can get it to go in every gear but 4th.

ju015dd · Dec 29, 2014

Drained the fluid, looked ok but till the last little bit came out. Def some metal in there. Also I had something larger at the drain hole but couldn't get it out and must have pushed it away from the area with my finger. Gave up for the day. Gonna call around and see what some shops say, or maybe wait and get a rebuilt one. Not sure what the cheaper route would be.

I shattered a shift fork in my yota back in the day. It was made out of cast aluminum and the gears just ground it up into powder like it was nothing. I remember splitting the cases, replacing the fork and then throwing it back in. I drove that thing for another 100,000 miles before cartwheeling it out of commission. My money is on that but not familiar with common failure modes in a ZF6.

Jasper is an option.

There is a little more to these, and parts avail ability can be a problem on some stuff. Midwest transmission is going to be your best bet for a reman. Good guys.:toast:

Thanks man. Just wish I could get it out of gear to get it home. Oh well may be doing a trans swap in the wood . Lol

Low range...

79jasper · Dec 30, 2014

Be careful trying to keep moving it. And definitely don't get pissed and just dump the clutch.
If only I still had pictures. Boss/PO few days previous said "oh it sounds fine, just go easy on it."

You could put some fluid back in it, put the transfer case in low range, and drive it to the road. Once on the road, put it in high range and drive it home, lol. Or call a tow truck. Or drop the drive shaft and pull it home with a tow strap, with the truck running, so you have power steering and brakes. Either way, you will want some fluid back in the trans, unless you plan on keeping the clutch pressed in with a board or something.
I still think you broke something with your shifting rails or fork, or something. You should be able to get it out of gear somehow, manually.

It's stuck in that gear. I've had this happen in more than one zf. Unfortunately there is only one way to fix it. I would start pulling the trans now. There isn't really another option. You can try and split the cases or send it to a shop that has the capability. I've done several. They are not a beginners transmission.

I was by no means trying to compare the zf-6 to a simplistic yota 4 speed with regards to easy of maintenance or servicing. I just felt like the shift fork was a part that can easily fail due to the way it might be made and was playing the guessing game like everyone else.

It would make sense to me that they would engineer that part to fail easily so that you can't cause much more serious damages if something wasn't quite right.

BTW, I miss that truck.

Gotcha

ju015dd · Jan 3, 2015

Got a local shop who seems reputable, building me a reman for 1750 plus tax. Question now is to get a new clutch while it is out. I know I have a single mass flywheel on the truck as of last time I had a clutch put in. Pretty sure it was a valair , but can't remember which clutch I went with. Clutch only has like 40 k on it and not much towing, just figured why not while trans is out.

ju015dd · Jan 11, 2015

OK guys, picking up the trans this coming Friday. My question is which pilot bearing to go with. I know the stock needle bearing is crap and heard quit a few bad things about the Kevlar. Any other solid options out there?
