Backstep801 Posted December 21, 2007 Share Posted December 21, 2007 I have a t2060 in a 95 dm690 with a e7-300. My problem is when I use low 1st gear (it has a air splitter). If I use it the trans pulls a fit and pops out of any gear at any time while driving. I have to quickly push in the clutch and wait for the motor to unwind then release the clutch. this seems to happen at anytime. after a while if I don't use 1st low it wont pop out anymore. I have no experience with this trans. got the truck about a year ago abd this started probably 3 months ago. I havnt been using 1st low for a while but would have liked it a few times. please advise all help welcomed and thanked.

Thank you. Anybody know of a online place to search and get parts for trucks? I notice your from Appleton WI what a nice place. I was out there a little over a year ago at the Pierce factory.

Backstep801 Posted January 1, 2008 Author Share Posted January 1, 2008 Well I pulled the top off the tranny and found the compound slider fork broken. Dug around with a magnet found the two pieces, rebuilt the air cylinder and put it back together with new fluid. seems to be working fine. Thanks for the help guys Quote Link to comment https://www.bigmacktrucks.com/topic/3211-tranny-problem/#findComment-15990 Share on other sites More sharing options...
