Does any body know of some one who repairs overdrive solenoids or do you have one for sale that works? This is for a 55 T Bird. Hemmings no help

Paul,



If you have the time/inclination, most solenoids can be repaired quite easily (unless the coils are broken/shorted). If you like, I could send you the repair info I used to fix mine. The unpublished instructions I obtained from an old FoMoCo dealer mechanic, and the 55/56 shop manual sections are all you really need. I also built a simple test jig out of plywood, so trans. mounting not required to operate/test (it must have adequate spring resistance, or proper functioning cannot be validated). If you have a spare battery & relay, the entire system can then be bench-tested. I have found that most 6V solenoids that were tossed as defective in the past (shop manual recommendation), will still operate fine without the high current resistance due to relay corrosion.

Daniel,



I am also interested of those repair instructions if You canve send them to me teros(at)dlc.fi . I have two broken OD solenoids. Contacts broken etc.

Tero (et. all),



Send email request to "dantinh62@kconline.com", and I will scan and include with reply when I get the time.

Tero/Paul,



I emailed the info twice, reversing the addressee & CC, but mail was returned undelivered both times. Let me know if either received it, or if you want it resent (alternate address?).

I just took one apart. Not much in there. I had one of the stand bolts stripped out of the base plate and I secured it back in with JB Weld. After I was done I pulled my daily driver up and hit it with the jumper cables and it clicked so I'm assuming it's gonna work. I plan on just hooking a switch to mine and bypassing the governor and just doin' in and out of OD with a switch. Hope that will work. I did that on a '57 back in the day and it worked. Check those replies to that T-89 site on "technical". A guy put a bunch of web addresses in there regarding schematics etc.

Tero,



Looks like it went through on the "webmaster" address.

Thanks Daniel,



Now I received it.

That will work but if at all possible, the solenoid needs to be wired in a series circuit with the governor.  Without the governor hooked into the circuit, the toggle switch will need to be turned off each time you come to a stop so you are not taking off in low overdrive.  And under normal circumstances, the transmission will also not go into reverse with the overdrive solenoid engaged but if you do manage to get it into reverse with the solenoid activated, you’ll damage the overdrive gearing when actually trying to move the car in reverse.

In the ones I've seen in an early (50's) Ford, yes it goes on the transmission. Do you know what they are off of?
By ltman - 16 Years Ago
Yes all of the trans are still in the cars I probly have 75 50s ford and mercury cars or more my freind is junking alot of old cars probly over 400 cars their are alot of good glass on them Hes leting me salvage all the parts off of them He not junking now due to the wether When the wether breaks these car will be crushed With some pointers from you guy i can probly save alot of good Parts
