97 geo metro lsi 2 door 4 cyl automatic a/c
I am in need of a 2-3 shift solenoid (with internal wiring harness?). The solenoid has intermittently acted up over the past year and now has finally quit working all together. It also turns the check engine light on. Checking the resistance with an ohm meter at the external wiring harness connector, one solenoid show about 3 ohms resistance. the other shows 30k resistance. Service manual says 3 ohms is ok.
If I have to take the pan down to check this out further, I want a solenoid at hand in case it is bad.
Not sure but I think all the auto transmissions used the same 2-3 solenoid. This also shows as solenoid
one in the service manual.
Thanks guys

Both solenoids are the same except for the mounting bracket. You should be able to pick one up from a tranny shop or auto parts store along with GM parts dept. I paid 70 bucks here from a tranny shop. Some are universal mount so be careful which tab you remove before installing.

I was hoping someone might have a core tranny, and it wouldn't cost that much.

Surfdav was nice enough to send me a valve body with both solenoids. Once the rain stops I will get the tranny fixed.

I had a bad 2-3 shift solonoid. Took all of 30 minutes to swap it out and back on the road with a transmission that shifts. About 20 minutes of driving and the check engine light when out too.
Once the pan is removed it is one mounting bolt, an electrical connector, and a new o ring to seal the solonoid. I did recrimp the connectors on both solonoids as I felt they had loosened up with age.

How do you know which solenoid does what? I got some from the pap and mine still starts off in 3rd. Do I need to reset anything? Also, my CEL wasn't on. Mines is on a 94 though.

Bell,
There is a 2 wire connector on the drivers side towards the back of the transmission. This is for the shift solenoids. They should show low resistance if you unplug the connector and test each wire with an ohm meter. Ground can be the transmission housing. If they check ok then it is a stuck shift valve and the pan will have to come off and the valve body removed and cleaned.

Did you ever get your GT running?

Thanks Fainya and yes I got the GT running. Cam gears were swapped and distributor cap was changed by the last person that I had look at it for a SOHC one. Actually, the SOHC cap is still on it. It's rigged to work. Just got it yesterday and for now, I'm just gonna drive it.
