96 Grand Cherokee tranny

[vaughnj]

I replace the transmission and rear-end on my 96 Jeep Grand Cherokee 6cyl auto 4wd. Everything went fine except the vac hose from the tranny to the engine. I don't remember where it attaches. There is the vac hose and a 4 inch piece of tubing hanging loose. When I test drove it, it wouldn't change gears til it red lined.

Someone go out and pop the hood on your Cherokee and look on the passenger side near the bell housing. There is a va line coming from the tranny. Where does it go?

are you sure its a vac hose,,not a vent for the transfer-case,,,,or vac to the transfer-case shift controls,,,,the trans requires no vac,,,high shift points should be corrected by adjusting throttle valve linkage from trans to engine

not sure about the vacuum line, but the shifting problem sounds like a really loosely adjusted TV Cable, adjust the Throttle Valve cable and it should take care of it.
