240sx auto trans problem help please!!!!!!!!

[pktj21]

hey do you why my 90 240sx ka24e sohc automatic trans RE4R01A will not shift in to overdrive or 4th gear after it warms up.20 mins after that it kinda will if you feather the pedal i have looked for answers i have even replaced sensors. help please if you know anything

could it be the inhibitor switch?

[mrgreeneyes]

could be bad fluid. drain, replace filter (kit is $12-14 at your local advance auto). if not then:

could be a bad trans

if its a bad trans, just 5spd swap it. SO much better

[pktj21]

dont have the cash for the 5sp swap. but i would love too. but for now i need this "automatic" to do its job which its not! i have changed fluid, filter, speed and throttle position sensor.

but i appreciate the help

Isn't OD part of the converter on these. Could be a bad converter OD.

[pktj21]

are you talking about the torque converter? i am not sure about that! i will check

[OutToWinPAHC]

Yeah, I don't know to be sure, some auto trans achieve the OD operation at the torque converter. Check into the FSM's and see if they say, it it does use the converter for OD the converter clutches for the OD could be shot.

OutToWinPAHC, I like your avatar. OP, I don't think anyone will know exactly what's wrong with it till its torn down. Seafoam TransTune. It will help a lil bit, but will not fix the problem. $7.69 retail.
