Transmission has been replaced by previous owner and the seal also on another instance. The overdrive light started flashing and the transmission slipping at low RPM's. Now the overdrive light is flashing and I have no forward or reverse movement and there is transmission fluid leaking severely from what looks like is near the inspection plug. Diagnostic showed misfire on cylinder 2 and a code for PCM solenoid. What is most likely the transmission issue? Is this the front seal?

Good afternoon,

Yes, it does sound like the front seal but that will not explain the flashing light and the slipping.

Did you verify the fluid level?

How long since you changed the fluid and filter?

If it is the seal, the torque converter, seal and the front pump bushing will have to be replaced together. You cannot replace just the seal or it will continue to leak.
