well my problem its my transmission was shifting first gear perfect. but the next she whit shift first gear , but when she hits her rpm for second it shift? my mistake i put 98 but its 87 xj

 

I'm not understanding. Can you explain a bit better? The shift to second gear has issues?

 

first gear is not working the second gear works

 

That happened to a friend when they used Type F tranny fluid. Lost first gear.
Automatic AW4

 

i gotta rebuilt the transmision. if so how did he got iit fix

 

Does first gear work if you shift manually to 1-2?

 

not yet. i stop the jeep as soon i had the problem

 

I have nearly the same prob on my 89XJ.. it locks the axels when i shift it to park but nothing happens when i shift to either gears that should move the car in any direction.. i should add that i have just lifted the heep 3.5" but it ran a day after that.. it started slipping as a burnd cluch would and then finaly no movment.. but it still locks in park.

 

Please translate into English. Not following your posts...

 

what i meant if. no i have to buy a new transmission. cause i was told to replace the Throttle Position Sensor

 

Try shifting manually. 1-2, then 3, then 4. See if that works correctly. Let us know what happens.

 

its shift perfectly whit no problem

 

Then the mechanical parts of your tranmission are OK. You have an electrical control problem.

Exactly what happens when you take off from a stop with the transmission in "D"?
What gear do you start out in?
Does it shift from 1st to 2nd?
2n'd to 3rd?
3'rd to 4th?
Are the shifts happening at the appropriate RPM, or does the engine rev up really high before shifting?

 

it skips first gear jumps to second
