Transmission Problem: Hard Reverse and No 1st gear - also sluggish acceleration
I have a U241E in my RAV4 and I've just started trying to diagnose it. I have tried 2 ECU's (one known to be working fine with the same transmission - no codes - no shift issues). However the ECU seems to not change anything. So I assume there is probably something physically wrong.
There was an error code for Solenoid B. So I dropped the pan (fair bit of black dust but not much metal at all), changed the filter, oil and SL2. Upon testing it the reverse was a bit smoother but still had a strong jerk and still no 1st gear (when put into 1). When starting in drive it is sluggish to accelerate (maybe starting in 2nd or 3rd?).
I was going through this thread: https://www.rav4world.com/forums/88-...ast-2nd-2.html
And also I found this manual shifting procedure to try: http://www.trav4.net/manual_shifting_test-655.html
As well as resetting the transmission memory (a/t initialization). https://www.rav4world.com/forums/99-4-3-mechanical/92414-have-dtc-p0746-pressure-control-solenoid-2.html
And I'm thinking I should try taking a look at the clutch packs and hard parts without extracting the transmission. I'm not too familiar with the U241E but I have worked on other transmissions. Does this seem viable? Is there a good reference for what might cause problems with R and 1 gears -- maybe a sprag failing?
Or does anyone have some good starting points? Thanks!
