Hello my name is Jason im from WV just bought a 95 grand Friday with transmission trouble. Problem is that it doesn't want to change from first to second gear unless you put the r.p.m. up to about 4500 or so and feather the throttly a little, but u can barley push pedal down and still won't change right even if rpms are up high. I did notice that the speedomemeter is not working will this cause the problem with shifitng gears. I checked fluid level its fine and oil is not scorched or smells burnt. Some people told me to fix speedo or it could be the transmission control module all help would be appericated in this fix. thanks for looking

 

sorry it is a 4.0 6cyl and i did run vin at dealer and they said it had a 42re transmission in it. Just not familar with the jeep game yet soon to be though thanks

 

100% it is your Vehicle speed sensor. no VSS no upshift. easy fix

 

where is the VSS located at output shaft on tranny or tranfer case and are they just one speed sensor thanks again

 

well went and bought one today a (VSS) and the guy before me already installed a new one i dont think he got the wiring right where it came with new harness does any one know how the wires goes back. i switched to wires around and still no M.P.H. readind and still acting funny on shift points HELP!

 

there should be two sensors. first one is for vehicle speed other is a kind of revolution sensor for automatic transmission. it was so on my pathfinder which i sold three years ago.

 

pretty sure it only has one. says Mitchell on demand anways but let me know if it has two.

 

thanks to all but it does have 2, A VSS and a transmission output shaft speed sensor so hopefully tomorrow i will go pick on up. One question the new VSS came with new wiring and guy put it on jeep before me i have from factory harness a blue/black stripped wire. A white/black stripped wire. And last i have a white/orange stripped wire. the new VSS has blue/black, solid orange, and white/orange stripped. it hooked up as follows. blue/black to blue/black, solid orange to white/black stripped, and white/orange stripped to white/orange stripped does this sound right?

 

well replaced trans output shaft speed sensor today and no help still now speedo. borrowed a scan tool for co worker and it wouldn't connect to my computers. Should i look for a TCM now or what i also looked a vss drive gear and seemed fine. would still like to know wire position on vss for plug in since guy wired up new sensor calling all help please someone with 95 JGC maybe look and tell me thanks..
