JA: How old is the transmission? Have you noticed any leaking?

JA: What is the model/year of your Ford?
Customer: 1995 4x4
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: I put in a Lucas product last fall, It helped noticeably. Problem recently returned. Yes I am considering fixing this myself.
JA: Anything else you think the mechanic should know?
Customer: The overdrive light flashes when the transmission exhibits these symptoms.

Hello, this is a 1995 ford bronco? f series? What engine and transmission is in the truck? Since the od light flashes, have you run a test for codes with a scan tool?

Hello, do you need more help with this concern?

Customer: replied 5 months ago.
I still want to tackle this problem. My truck is a F150 with a 5.8l. I have not retrieved any codes. I don't know how many miles on the transmission. At least 120k.

Ok, since the od lamp is flashing, a check for codes with a scan tool will need to be done to find out what transmission codes are stored. It could be an issue with a solenoid body or something else. Once you know what codes are stored will help pinpoint what direction needs to be followed to help fix this concern.

Gene, I'm still here. DTCs refer to trans temp voltage(636) and insufficient VSS signal. ( I forgot that number) Where are these sensors? and where are their parameters?
Customer: replied 3 months ago.
oops -- What are their parameters?
