My sis 2001 4 cylinder automatic honda accord had harsh up shifts from 1 to 2. Loud clunk sound on down shift 2 to 1.
No codes.
The dealer said rebuilt tranny for 5k dollars.
Diagnosis was just by test drive.
Instead of 5k i decided to get fluid flushed. Did not help much.
Then i thought perhaps the transmission mounts are worn out at 187k miles and winters. Sure enough one was really bad. That has made improvement in it downshifts from 2 to 1 well enough be slightly happy.
I took the double humps torque converter solenoid. The screens were really plugged. So i went ahead and changed the screen. No difference. Now there are two more solenoids underneath this big one with the replaced screen. I think they are called shift solenoid b and c. I think they are used in 1 to 2 shift. What if these were plugged ? What would be the symptoms?
My hands are too big to get to them without some serious effort on another day. Anyways any inputs regarding this will be much appreciated.
Except 1 to 2 upshift all shifts are flawless including overdrive on highway.
