Where is the lock up solenoid?
The lockup solenoid is under the cover on the left SIDE of the transmission.
How do you remove a Geo Tracker transmission?
Place the block of wood on edge underneath the rear cylinder head of the engine to support it, roughly between the distributor cap and the bulkhead. Make sure the block of wood supports the engine before you remove the transmission. Lower the jack slowly to remove the transmission from the Geo Tracker.
Why did they stop making the Geo Tracker?
But in 1993, after just 3 years of existence, it was discontinued due to the refocusing of Isuzu on trucks and SUVs. The hardiest model produced by Geo is the Tracker; it is a part of the original lineup in 1989 and stayed until 2004 when the brand itself was discontinued.
Where are the solenoids located in a transmission?
When the TCM triggers this coil, the plunger moves, allowing pressurized hydraulic fluid to flow to certain parts of the transmission. This allows the transmission to shift into the desired gear. There are two or more shift solenoids inside your transmission. The solenoids are typically integrated into the transmission valve body.
Is there a lockup relay on a 4 speed tracker?
When you said ’96, with OBDII codes, I assumed your tracker to be a 4 speed. If it is a 4 speed, there is no lockup relay; the function is provided by the TCM. The two items which control TCC lockup are the TCC Control Valve and Solenoid Valve No 2 (TCC Solenoid Valve).
Can You unplug the solenoid on a GM converter?
Generally, if you unplug the TCC solenoid at the transmission and the symptoms go away, you have found the problem. But sometimes this can be misleading because you don’t know for sure if it’s a bad solenoid, dirt in the valve body or a bad signal from the ECM.
What should I do if my GM converter lock up?
NEVER run the vehicle in gear when supported only with a jack. Chock the drive wheels and apply the parking brake. In addition, some of the tests (test #11 and 12) require the transmission be opened and the valves are physically inspected. I do not recommend that you do this.
