93 240sx auto transmission, delay shifting between 1st and 2nd gears, RESOLVED

[cellogig]

I am writing this for the archives in case someone has the same issue.

I would like to thank this forum for a post about the revolution sensor concerning the delay shifting or no shift at all between 1st and 2nd gear. Unhooking E-13 module that leads to the revolution sensor. That post has gotten a little long so i will state it simply.

I could have changed many different components out or rebuild the transmission, which would have cost $$$$ but replacing the revolution sensor part #31935-41X20 for about 120.00 including labor has made all the difference!! This may not resolve your problem but i would start with this part. The sensor is located on the drivers side towards the top of the transmission.

thank you all

what did it take to get to it?

I had that problem, but now I'm having a new issue. It doesn't like to shift into 3rd until I let it ride in 2nd for a few blocks then it slugs down and shifts.
