HELP!!! TH350 Stuck in 1st gear!!!

[88chevota]

Well now it looks like it will be a little longer before i get it out on the trail. I was driving around today running errands getting ready to go on vacation tomorrow. I come out of Target and put it in reverse to back out and it starts moving forward. I thought oh must be my shift linkage... NOPE! kick down cable? NOPE! vacuum line... NOPE!!!! AAAAAAAHHHHHHHHH! so I push it out of my parking spot thinking my reverse is shot. start driving and realize i am stuck in 1st gear!!! I am actually stuck in 1st gear no matter where I shift it! Even in park. The park lock-up works, but I can tell I am stuck in first gear because if I rev it at all it feels like it wants to go and it won't rev freely. That feeling like you have your foot on the brake and give it a little gas while in gear. Same thing in park! CRAP! any ideas what the heck is wrong?

drop the pan or drain the fluid and check for metal. had a similar issue with a th350 i put together. felt like it was going into first and reverse almost like a trans brake so i dropped the pan and found alot of little metal shavings. somthing shredded and the valves in the valve body were suck because of the metal shavings. my guess is a valve body issue. good luck .

 

[88chevota]

Found the culprit. There is a small s-hook that connects the shift linkage to the shift rail in the valve body when I dropped the pan I saw the hook just dangling there. Works great again.

had the same problem. easy fix luckily

 

[88chevota]

yep definitely easy here is a pic. i would think there is a better way to attach this to make sure it doesn't happen again. that would suck to happen on the trail.

 

[wizzo]

yeah, mine broke on the trail, luckily it was at the end of the day and i could still load it on the trailer.

 

[88chevota]

I don't trailer mine so that would really suck!!! I already had to push it out of a parking spot and drive it home is 1st gear for 25+ miles. anyone know of a permanent solution?

 

[88chevota]

just happened again. Seriously anyone have ideas for a more permanent fix.

could you drill a small hole through the end of the "S" hook and add a cotter pin to keep it in place?
