Transmission problems 42RLE
Hi!
My transmission 42rle started having problems. If I put it in 1, it runs fine. If I put it in 2 it runs fine. If I put it in drive, it goes from 1 to 2 fine most of the times (sometimes it gears rough), but when going into 3rd it gives no power and just revs. I tried opening it up and cleaned the solenoids in the solenoidpack, but still same issue.
What is the next thing to check? Could it be the EPC solenoid? Or is the Torqueconverter the next step?

well, right now it would come out pretty clean since first try to fix the problem was change oil and filter. Then oil hot flushed again when I took out the valvebody do clean the solenoids in the solenoidpack.

Looks like you got this figured out. I personally never thought Automatics could be such a pain. I Youtubed this and found a good video. You might have already seen it. If you had the solenoids out already, how do you know they we're good or bad when you put them back in.

from what I’ve seen on youtube, the solenoids in the solenoidpack can ger gunked up with junk. You can hear if it moves freely or not by chaking it. 2 out of 4 was gunked up in mine so a demagnatizer, a bit of brakeclean and compressed air got rid of the junk inside the solenoids.

To me, the o-rings look like something from a hardware store for faucets. And those wear out within a couple of years. And leak! So if you had black gunk, most likely it's from O-ring wear. Me personally , I'd replace the solenoids if you're still experiencing the same problem. And then it could be the control modules.

Could be clogged port around one of those valves. Can the valve assy be removed?
Oh, never mind. It looks like you already had that out.
