No reverse.

[eaglewrench]

I had 2-3 shift flare up problem on my 95 Explorer. I think it's a 4R55E. I just went through the value body. I put in a Transgo kit and replaced the intermediate and overdrive servo pistons and the large o-ring on the low/reverse servo.

Now I don't have reverse. Reverse engaged for a few minutes while up on the hoist, but next time I put the shifter into reverse position, nothing. It appears to be shifting in forward gears okay. O/D light is also flashing, but it appears to be shifting in and out of O/D when I press the disengage button on the shifter.

What did I do wrong? Please help! Thank you!

Welcome to this forum! I've moved your post into its own thread in the transmission section. Double check your work. You could have a problem with the reverse modulation valve, torque on the valve body gasket or the low/reverse band might have shifted out of position.
