97_Mack Posted September 2, 2023 Share Posted September 2, 2023 My father's truck is stuck in gear after his foot slipped from the clutch. The shifter is in neutral but it appears stuck in the transmission? Possibly elsewhere? Any advice would be appreciated. Quote Link to comment Share on other sites More sharing options...

mechohaulic Posted September 2, 2023 Share Posted September 2, 2023 can't say ever heard one like that. not to be harsh but a few details would help ::: truck was loaded : going uphill/downhill/ .. like Jojo stated =model numbers - info of any kind not to mention the all important pictures. clutch still works normal ;; does it go to floor easy due to cable pin off ??? new /old clutch ?? just a few examples of helpful info.

Joey Mack Posted September 2, 2023 Share Posted September 2, 2023 If it is an old Mack, I know that I have made repairs for this reason, a few times. typically related to wear on the shift tower and slots in the forks which allow the end of the shifter to slip out of a fork and into another fork before disengaging the first fork, hence, '' in 2 gears at one time'' 1 Quote Link to comment Share on other sites More sharing options...

I believe it is a 1997 CH613. It was in his yard, no trailer. He was attempting to move it when his wet boot slipped off the clutch. The clutch does still work as far as I know. I don't have any other info at this time. He just asked if I could look online for a solution before deciding if he has to bring it to a shop.

mechohaulic Posted September 2, 2023 Share Posted September 2, 2023 i would recommend checking a couple things before $$$$$ at a dealer. with one in driver seat another under neath AND FINGERS /HANDS CLEAR watch movement bottom side while driver pushes clutch >WITH ENGINE OFF . possibly slam dunk of clutch sheared a frayed cable ? at least you can see if the clutch arm on trans is moving. bolt on clutch arm may have been loose and arm moves clutch cross shaft in bell housing isn't. which is another option::'97 is tooo new for me ; don't know if the bell housing even have an inspection hole any more. flashlight and safety glasses look up inside while clutch being depressed. course before all this I should have asked (as Jojo did ) info;; is it a standard transmission at least ???? 1 Quote Link to comment Share on other sites More sharing options...

mechohaulic Posted September 2, 2023 Share Posted September 2, 2023 don't forget the pictures .LOL mack trans should have ident stamped in side of case. hopefully you will get it rectified. when you do a follow up on here always helps the next guy. even yrs down the road. i spend a lot of time going back to post from yrs back. interesting how many times a question comes up related to earlier post.

If you can move it into gear, then you have bigger problems, than just a shifter interlocked. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Joey Mack Posted September 2, 2023 Popular Post Share Posted September 2, 2023 (edited) If it's a CH. Pull the floor pan, then pull the stick out, 4 bolts for a Mack tranny, 6 for an Eaton/ Meritor then put the shift forks in neutral. Look for rounded square slots on top of the shift forks. They are suppose to be square with sharp edges.. they get rounded over time due to not shifting a correct 'H' pattern, basically sliding the shifter in a 'Z' pattern.. good luck..

tjc transport Posted September 2, 2023 Share Posted September 2, 2023 yup, what Joey said. pulled many a shifter on the side of the road, and stuck a BIG screwdriver down in the top of the trans to put the shift gates back in neutral, than stuff shifter back in cause the boss was too cheap to have the trans rebuilt and trucks had a gazillion miles on them. 1 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

mrsmackpaul Posted September 3, 2023 Share Posted September 3, 2023 As these two jokers have said, pull the floor out, pull the stick out Im guessing thr gear stick has slipped past a gate Should be relatively easy to correct as has been described already Paul Quote Link to comment Share on other sites More sharing options...

mechohaulic Posted September 3, 2023 Share Posted September 3, 2023 so majority vote is foot slipping off clutch pedal not related to stuck trans?? have removed a number of shifter levers for problem mentioned to do exactly stated with large screwdriver to reposition trans to neutral. don't remember any due to slipping clutch pedal. 1 Quote Link to comment Share on other sites More sharing options...
Geoff Weeks Posted September 3, 2023 Share Posted September 3, 2023 The problem with diagnosing on the internet, is you are relying on someone else eyes and judgement. He said "as far as he knows" that the clutch is working. I take him at his word. It would be easy to tell if the clutch is working, as the truck would move if the engine was running and wouldn't if the pedal is pushed. SO I doubt it is a clutch problem barring more info pointing that way. 1 Quote Link to comment Share on other sites More sharing options...
JoeH Posted September 3, 2023 Share Posted September 3, 2023 I don't think clutch linkage breaks when you pop the clutch. That usually breaks other things. Input shafts, crank shaft, output shaft, axle shafts, counter shafts.... Quote Link to comment Share on other sites More sharing options...
JoeH Posted September 3, 2023 Share Posted September 3, 2023 Personally I also don't see how popping the clutch bumps the shifter out of the gates... 1 1 Quote Link to comment Share on other sites More sharing options...

Often a hand on the stick when the clutch is pressed, whole truck torques from the dumped clutch and the guy is still "hanging onto" the stick. Gears under load and a pull on the stick, something is going to happen. Just popping a clutch with no human in the drivers seat, I would agree with you, but don't factor out the human! 1 Quote Link to comment Share on other sites More sharing options...
