P1000 Transmission shifting hard

[Mimbs15]

Alright let's see if I can sum it up. 2020 Pioneer 1000 prolly about 5500 miles give or take. Here recently it started shifting hard at times, sometimes it won't. It would shut off sometimes while downshifting amd throw code 62. I went in and changed the shift valves and the dual clutch shift valve. Seemed to fix it about 2 weeks, started shifting hard again hit or miss. Mostly once it got good and warm. Now it's shifting hard majority of the time even at low speed. So I just replaced the 3 shift solenoids. Same problem. I just a

Have you checked the grounds, more specifically the one directly next to the starter.

Be sure to put a wrench/socket on them, as they can seem tight then loosen with actual force applied.

If that doesn't fix it, it may be the larger PC solenoid in the valve body.

I have not checked the grounds but I willl.ck that one 2mor and the others. I've had the valve body off, what is the PC solenoid?

At the top of the valve body is a large solenoid that comes in from the side, that is what applies the clutches.

Usually that code isn't a symptom for when it goes bad though

That may have been the one I replaced then. It's kinda of on top of the shift valves. If it is that's the dual clutch solenoid

There's 3 smaller ones at the bottom that move the valves/oil around

The large one at the top actually controls finally oil flow/pressure to apply the clutch

Yeah I'm pretty sure those are the ones I changed 1st. They were the cheaper ones, other than the dual clutch one. It was more.

UPDATE! After the 3 new EOP sensors or shift solenoids that are located on the bottom side of oil pan. Shifts even worse. Whole slowing down and as it downshifts when it hits 1stbut will die amd throw code 62.. I'm at a loss.. Help Greatly Appreciated

I assume noone has this issue.. this thing is kicking my butt.. help greatly appreciated

I attached the trouble shooting pages for code 62 from service manual. Looks like You guys are down to the linear valve solenoid, clogged oil passages or faulty PCM. If you know anyone with a pioneer 1000 close by you I would suggest buying them a case of beer to swap your PCM into there machine to see if it does the same thing. Its usually best practice to swap suspected bad part to know good machine to avoid frying there good one if there was something to cause it to fry the circuit on theirs. Hope this helps you guys.

Yeah I've got the service manual, I've tried PCM no change.. and I put a new linear valve as well with a new. Still the same..I'm at a loss. Got the clutches out now and see nothing out the ordinary. No discoloration and still felt on them.

Update, I pulled the clutches and no signs of anything bad. No discoloration or blue looking on the disks . All look fine. Now it's all back together and when i put in reverse or high it's hung and wont cone ouy.. wthell now.. I didn't mess with anything else. Other than putting a lock bolt on them 2 gears where the one wouldn't turn.. help.. and it won't relearn the clutch.. Help please

Sounds like you didn't get the clutch assembly slid all the way onto the mainshaft.
