Hello all have a 71 F100 with T89-OD need info regarding mechanical kickdown from gas pedal to switch on engine side of firewall to OD solenoid.From what it appears everything is there but dont see how this setup can engage the switch.Can anyone take a picture of a working setup so I can try to figure this out?
Also was looking at solenoid on OD and tryed taking cover off to check contactors and tranny oil was pouring out bad seal or gasket filling solenoid up with oil.Where can I find gaskets for these? Some pics of linkage in question nothing actually comes in contact with it.Rod returning from linkage to firewall just goes to the mount not the spring loaded switch.

Is it all original? Any chance it had the gas pedal changed? The six and V8 pedals are different lengths, just a thought. Ebay has parts for these, not sure if there are any other sources. Are you sure T89, not T85? Is the tail an R11, or R10?
Great ideas have always encounter violent opposition from mediocre minds.
Vin has code B which is T 85 or T86 but casting on tranny says T89B-14 and yes OD says R11.I suppose its possible pedal was changed but unlikely,wouldnt think it would wear.Odometer reads 55K and interior shows it hardly any wear on pedals seat like new door hinges still tight.So do you think there was an extension off end of pedal rod that contacted switch?

Two things that will hopefully help, first the T-89 is basically a T-85 and the numbers are used interchangably. the T-89 can be found in any 56-71 3 speed overdrive Ford pickup and the door tag code will be for a T-85. Next, looking at your picture it appears to me that the throttle linkage is actually broken. I think the shaft from the pedal has slid sideways into the cast potmetal bracket on the firewall. It is possible that the entire part is broken but it looks more like it has slid into the housing too far because the retainer washer slid over the bumps or the bushings slid to the side. Hawkrod
that gas pedal om;y has one hole in the pedal end. and it is offset from others i have seen. it loooks more like the pedal came from a dentside. the dentside pedals only have on hole and the aren't as croocked as ours are. they are more straight when they come out of the firewall.

Good eye, yes, you are probably right. The pedal broke and they replaced it with the wrong one. Hawkrod
Interesting so pedal shaft does actually engage and disengage the switch from what you are saying?I thought perhaps something came back from bracket on intake manifold.My dad still has a 72 bumpside on the farm with a three speed in it but I dont think it has OD.Perhaps the other trucks pedal rod will work.

boatcarpenter, i have a 70 with the t-85 set up, and yes you have something there missing. Looks like the rod from pedal rod to carb has been changed. With your int od knob pushed in your od should disengage when you get on the gas pedal. Let off the gas peddle and tranny will freewheel. Int knob pulled out and that disengages your od and you basically have a reg 3-speed tranny.Looks like maybe an ear that engages and disengages that switch is missing.
Do a google search on borg warner t-85n od transmission or r-10 and r-11 od and you will find all kinds of info and wiring diagrahms on these, although you have a ford, these trannys came in many different vehicles. It is considered an electric controlled od.
I can take some picks for you this weekend if you can't figure it out. If it has been changed i doubt you will find the part you need. You will have to fabricate something unless a member here has a donor with the same pedal setup.
As far as the grease leaking from the selonoid, it is most likley coming from one of the gaskets where the tranny comes apart or the o-ring behind it.
A guy in azle Tx, rebuilt my tranny and has some parts. Give him a call. Charles Smart. B & C transmission. 817-270-8210.
Hope this helps you some.
Ok boatcarpenter looked at mine when i got home. Your pedal rod should have 2 holes, one for the linkage that goes to carb and another below it. Attached to the bottom hole should be a 1" wide by 2" long piece of metal bent in a V shape.
One end bolts to pedal rod and when you let off the pedal the other end should come back and press the spring switch. It would be easy to make one out of flat bar. I would shoot you a pic but it's dark here.
Looks like you pedel rod is missing the second hole but it think that it would be easy to fab something that would work. Your main goal is to have somthing that comes back and depresses the switch when you let off the gas
Hope this helps.

Thank you for clearing that up. I had thought the pedal hit the switch itself. Thanks, Hawkrod
So from what im gathering so far is that spring on switch should be depressed when no pressure is on pedal?I was able to briefly take a look at it before work this afternoon and it does have only one hole in pedal shaft so something will have to be fabbed up for it.Will have to dig through scrap barrel at work tomorrow and find a piece of aluminum bar stock
As to the solenoid as stated in initial post had tryed to take top cover off from unit where wires run into it and oil was pouring out.From what ive found so far pretty simple and durable part so should be able to clean contacts up but there must be a bad shaft seal for engagement rod or a gasket will have to be made.
Have found quite alot of info for these on this site and http://speedprint.com/deves50/overdriveindex.php but unfortunately no pictures of this switch on the linkage,so would appreciate a picture if someone gets a chance.Thank you guys for info thus far

That is correct metal ear should come back and press spring switch when you let off gas pedal. I will try to get you some pics of that linkage and switch ear as soon as i can. From what i know on the solenoid it does have contact points in it and they can be cleaned and adjusted.
