      hey guys, i've got a 1996 explorer 4.0 auto 4x4 that i'm trying to replace the modulator on. i've followed the advice of some of the threads here by going thru the access panel under the carpet but i don't see a modulator anywhere behind the two servos. anyone know if it could be somewhere else? do all explorers have them? i'm baffled. thanks for any help

      no modulator

      I believe that you have the 4R55E transmission on your 1996 V6 which is electronic shift controlled by the PCM. There is no modulator to find. The modulator was used on the A4LD transmission (1991 thru 1994).

      thanks for your reply. kind of a bummer to find this out after i have already torn it apart. autozone even sold me a modulator for my 96. do you know if there is another part that can cause a delayed shift from 1rst to second? it doesn't happen all the time and has been doing so for about 6 months. it's my daughters' truck and she lives in jacksonville so while she is home for holidays was hoping to get this and a couple of other problems sorted out. truck doesn't get the maintenance it used to since she moved. anyway, thanks for your help!

      ATF level?

      I assume that you've checked the ATF level and it was normal.

      You may want to confirm what type of transmission you have by checking the door plate under the heading TR I believe. I'll have to look up the code for the 4R55E and the A4LD since I have the 5R55E.

      Is your check engine light on? If so, have you read the diagnostic trouble codes?

      transmission codes

      Here are the transmission codes:
      T (1992-1995) A4LD
      T (1996-2001) 4R55E
