Transmission Solenoids

[Kenney Kelley]

How does one check solenoids if they don't have a factory computer? Someone told me that's how you check them. Or do you just buy new ones Thank You Kenney Kelley

You mean the transbrake one? Internal or external? A transbrake solinoid is basically an electromagnetic switch. Give it power and ground. If it clicks it's OK. If not Not.

You can use a wiring diagram and go to the connector at the trans or you can pull the pan to access them. Then you can use an ohm meter and or run jumpers to see if they activate, you can hear them click. Now that will check the solenoid but you won't know if there is a problem in controls or wiring.

It depends what type of solenoid you have , Some solenoids are on/off valves , some regulate a pressure , and most external trans brake solenoids provide a force on a valve . The on/off and trans brake solenoids can usually be checked by just energizing them with 12 volts. The solenoids that regulate a pressure need a voltage source that cycles on and off at a given HZ but gives you the ability to control the time its off verses the time its on . Do you know what type of solenoid you have , or what its used to control ?

Its a 350 Turbo it's a Stock elim transmission so no trans brake. It didn't shift last Friday at Gainesville it didn't act right on the burnout or when it left the line. So we loaded it up and came home. I need to put it on the lift and pull the pan and go from there. I thank both of you for the Info you have provided. Thank You Kenney Kelley

I thought there weren't any solenoids in a T-350? Something I am missing? I know I'm a polock, but still.

I thought it was 200 but my brother said it was 350 but as soon as I get it on the lift i'll know. Thanks Kenney Kelley

Sounds like your trans has a aftermarket "E" valve body . The type of solenoids used in this type of racing vb are the on/off type .

Did it shift at all or just stay in one gear ? Does the car have an e shift controller like the one Turbo Action sells ?

I think the car has to be 1988 and up.Must have electronic fuel injection or a super stock car

It's a 95 Camaro with a T-350 Pro Trans Transmission
