I have a 1988 Bronco II with the A4LD automatic transmission and 47,000 orig miles and sat for 12 years.
The transmission shifts great from 1-2-3-4 but acts erratic at torque converter lock-up. Sometimes the TC will lock-up and stay locked up as long as it needs. Other times it will rapidly kick in and out of Lock-up even on a level or slightly downhill road. I talked to a transmission shop today and they said it did not sound like a transmission issue but and engine issue, like a sensor, brake light switch or an RF signal picked up by the computer. The engine runs great and I don't get any CEL. The transmission has no leaks and the fluid is full and very clean. Can someone help clarify ?
Thanks.
