Hello all-
over the past few years, my overdrive became finicky, and would usually only start to work after everything warmed up, maybe 10 to 15 mins of driving. Before it warmed, hitting the OD stalk produced a dim light on the OD versus a bright light, and a decent draw on the Amp meter. After a few attempts, it would often begin to work well and not be an issue. A few attempts became, many attempts an longer drive times and now it basically won't function.
My initial thoughts were electrical, but after a lot of sleuthing, it seemed like that was not the issue. I swapped relays and solenoids etc.. to the same results. I adjusted the switches in the trans that prevent/allow engagement in the correct gears etc...to no avail.
I thought it might have something to do with oil viscosity so I changed the oil entirely and confirming it was at the proper type and level. Did not affect the OD.
So today on a drive, I was trying to figure it out, and noticed that it will engage easily and consistently at a dead stop. Both with the engine running and with the engine off. And by engage, I mean the OD light comes on strong, the voltage flicks and returns to normal, and you can both hear and feel the solenoid clunk as it moves.
I had been playing with odd theories about maybe it only engages when oil pressure is high, or low, or if I was in a sharp left turn, etc.. because it was so random when it would decide to engage. That is when I figured out it really loves to work perfectly when the car is stopped. Neutral or in gear with the clutch depressed seems to make no difference. I then began to see if it would engage at all at speed, and figured out it will consistently engage in both 3rd and 4th up until about 10-14 miles per hour, and then it reverts to the dim OD indicator light and no true function.
I have done some searches to see what I can find from this awesome community, but cannot quite find anything that would explain this. I do not know these DeLaycocks well enough to have much in the way of a theory as to what night be happening.
I am going to re-clean all the contacts and connectors, make sure the grounds are good, and try to start fresh with swapping components again to see what's going on, but also wanted to put this vexing situation out to this smart group of experienced folks and see what you all might suggest.
Sorry for the book, and many thanks in advance for any thoughts or advice.
