jakebrake86 Posted November 28, 2012 Share Posted November 28, 2012 I have a friend with an 87 R686 with a 2 valve 300 and a 2 stick six speed I swapped in it out of an '82 model. He bought the truck from me a couple of years ago and hasn't had any trouble until recently. The compound stick is jumping out of direct, but it isn't making any unusual noise. He's convinced the transmission has got to go, but I'm leaning towards it being something simple. Could the problem possibly be in the plunger on top that works the compound shifter?

David Posted November 28, 2012 Share Posted November 28, 2012 We had one years ago that would jump out of fifth. Turned out to be loose bell housing bolts. Quote Link to comment Share on other sites More sharing options...
Lmackattack Posted November 28, 2012 Share Posted November 28, 2012 If I recall there is also a detent for that stick. If its worn a bad bump can knock it out whith slack in the gears. Quote Link to comment Share on other sites More sharing options...
jakebrake86 Posted November 28, 2012 Author Share Posted November 28, 2012 David, it started jumping out a couple of months ago, and upon inspection the bell housing bolts were loose, sure enough. They've since been tightened up, but the problem persists. Quote Jake Link to comment Share on other sites More sharing options...
David Posted November 28, 2012 Share Posted November 28, 2012 Check the bolts again. Is there any gear oil leaking at the input shaft. You may have bearing and/or shaft damage from running with the loose bolts. Quote Link to comment Share on other sites More sharing options...
