Have now solved this problem fingers crossed.
Replaced all of The solenoids since i bought a complete valve body. Now it shifts normally. But i suspect The SL solenoid was stuck even tho it gave correct ohms.

Hopefully This might be helpful for others aswell!

Did put 12v straight to the solenoids, and the SL solenoid did not click at all.

Today still stuck in 1st gear.

Took it for a long spin suddenly it went into limp mode so quickly reseted code with the key 4 times. did that like 3 times then suddenly the gearbox went back to normal and started shifting through all gears like nothing happend. continued driving for 1hr to see and ...

More testning. Replaced tcm no difference.
Tried to start and take off in L. To around 3000rpm 30km/h then switched to 3 i felt it shifted second then 3rd Quickly afterwards drove fine around 70km/h then switched to D shifted to 4th. Around 90km/kmh i felt it engages The OD. So seems like the tranny ...

Okey Thanks! So only need to get speed signal from ABS then i suppose? Hope Someone could chime in if i need The tcu aswell. They seem identical same pnp switch. Same rpm sensor on The top. But not The same speed sensor on The driveshaft what i can see externally.

Hey wondering if a v70 aw50-42le fits in a volvo 850 1995 t-5r.

Im asking because i dont seem to be able to find a trans from a 850 t5 in Sweden. But if i can get a trans from a v70 turbo to work in my car its easier to find.

Possible?

Have checked The solenoids S1 and s2 is 17ohms dunno if 2ohms over would make a difference. Rest of The sensors within spec.

When it goes in limp, i can select 3 and it engages 3rd gear and put it in D it engages 4th.

Everytime i restart The car it still only change gears to 2 second gear. And it ...

Hey

Recently replaced the Shift solenoid S2 and then the gearbox worked fine for a few months, but now just recently im starting to get the 3-2-2 incorrect gear ratio code.

Everytime when i start the car its not slipping or anything but when it should shift to 3rd gear it just doesnt it goes into ...

Thanks was hoping there could be a easier fix!

Btw was cleaning the car, and the driver seat was working perfect. moved it forward and backwards to clean under it.
But then later when i was gonna drive it i cant move the seat forward. Only by pressing the Memory button 1,weird.

I swapped over The replacement cluster, but kept The old mechanical unit. Now everything works including The diagnostic. And was able to reset The servicelight yey!
If you say True mileage follows The cluster i think i have to live with that.. Sadly.
