I have a second 98 red xj im fixing up and I just got it running the past few days, it sat for years before i bought it and the alternator had froze up so i replaced that and the battery and shes running smooth.

ALSO- when i bought it the owner had told me something was wrong with the trans.

OK so when I try to drive down the road from my house it wont shift out of first till high rpms or if i play with the throttle some and it seems to do it into 2nd also.
all the gears seem to work just fine. I got her up to 55 and could not feel or hear any abnormalities.

so please help me out guys, im at a loss for what to do I just replaced the TCS today and that didnt even help..

 

What did you replace, the TCU or the TPS? There is not a TCS.

Whichever you replaced, (if fluid is RED in color, does not smell BURNT and is at the correct LEVEL on the dipstick) I'd try the other.

 

the TPS sorry.
the fluid is good. clean and no smell.

 

also i just drove it down the road again. its only 1 to 2nd that is taking too long between the shift. and if i accelarate quickly and let off the throttle then hit the gas again it gets it to go into 2nd and after that its all smooth.

 

tcu? transmission control unit? if so im not going to spend over around $140 or more for that... maybe i can try the junkyard? what does it actually look like an where is it located?
