so, i can't get any help with this over at jeepforum.. but ANY answers would be amazing..
i'm just gonna copy my two posts.. thanks

could someone help me with a problem i'm having?
my jeep wont shift out of second gear. [limp mode?]

this happened very suddenly, out of a clear blue sky, while i was driving...

i'm praying it is the input/output speed sensors..
i pulled codes for

incorrect gear ratio -3rd gear
incorrect gear ratio -4th gear.

part numbers for these sensors anyone??
similar problems?

IS IT SAFE TO DRIVE IN LIMP MODE???
[in order to bring to a shop without towing it]


...

i drove it to the shop today.
they are probably busy, so wont get around to it till next week...

anybody? suggestions, comments..
you think ill need a rebuilt tranny, or is this another case of solenoid/speed sensor failure?

This is from an 06 KJ Parts book but it might be the same number for earlier model KJs, but here it goes,

Transmission output speed sensor P/N: 52584001AA

Transmission input speed sensor P/N: 04799061AB

Sounds like you blew the side plate off the valve body in the trans,or the solenoid pack went south.

are either of these expensive fixes?
i read about the speed sensors costing $30-50
not sure about the others...

thanks

If the side plate blew off it may be a simple $30 fix,if the soliniod pack went that's about a $750 fix.

It's probably best to let the professionals diagnose this problem by actually taking it to the dealer or your mechanic so that they can physically inspect the transmission to see what went south.

Not saying that we can't help you on the board here, but if the transmission is in limp mode, it needs immediate attention and poking around at it with parts that might or might not fix the problem could make matters worse.
