Title: Transmission questions
Post by: ChrisV289 on January 07, 2018, 06:28:40 PM
Tying to determine if the bell housing and torque converter are original to my car. The transmission has the right numbers and tag. Also I found a wiring clip on the side that didn't have anything in it. It was on the driver side. Any idea what it was for? Also there was another clip on the passenger side. First time looking at this transmission this close ever on the car.

I had intended on replacing my vacuum line so I had done a little research at one time. My Vacuum line is pretty bent up and isnt running the original course but from what I remember however I believe the passenger side is for the Vacuum line before it transitions to rubber. The driver side I've seen a clip for the Neutral safety switch however in a different position if I'm looking at that picture correctly.

The clip in picture #5 is for the hard vacuum line that attaches to the transmission at the modulator

The clip in picture #3 looks to be for electrical so the loom going to the neutral safety and back up switch I would assume. Will look at some examples to see if I have a related picture.  No external ID tag on the trans?

Looking through my pictures and comparing I think your trans may have been rebuilt or at least partically disassembled at some point in the past. ID tag is missing and the wire retainer on the drivers side may have been reinstalled at a different point. Only other example I found had that bracket (looking at it from the drivers side ) at the top upper left rather than the upper right and holding the wire loom for the trans switch.

As for the other bracket here are some pictures to illustrate

Example from same plant and production period as your car. You can make out the line and clip at the top center of the picture below

Hi Jeff,

I have the tag. I took it off so the rebuild shop does not lose it and to clean it up.  What direction should the wiring loom clip be?

Sorry for the quality - this is an very enlarged picture of a pretty small jpeg. Appears to be pointed forward while attached to the front top mounting bolt

Thanks Jeff. And I assume that is where the tag should go? Mine was on the other side in pic 4.

 I have seen the tranny tag attached in the same area as yours Chris, in your pic #4? Can we have confirmation whether that that is the exact location these tags are supposed to be located or the opposite side as Jeff stated?? Not only for 65' but for 66' (which is my year).  ;D I was lucky enough to find the correct tag for my C4 but  now I'm unsure where it is supposed to go.

Chris sorry - missed your ID tag attached over on the passenger side and thanks to Hipo giddyup for pointing that out.  The vast majority of automatics it seems have been out and rebuilt (reason why there is a lack of paint marks normally still on them) so many pieces can be found in different locations. Looked at about a dozen of 65-66 C4's this morning and not a one had the electrical wire loom clip on them. Many had the ID missing  as well as the vacuum line clamp also gone.  Seems that the 66 versions were pretty consistant with the location of the ID tag on the passenger side while the 65's I found them on either side. Not a big sampling and realize that the location could have been swapped especially of the bolts for the servo and the governor are inter changeable - since the tag likely stays with the bolt when removed

Jeff, do you think the torque convertor is original? Debating if it should be replaced, kept, or replaced but retained. Thanks for your help so far. I haven't seen any markings on the transmission yet. The mount is original and has a yellow dab facing towards the rear.

If you're going through the process of rebuilding the transmission, I would highly recommend rebuilding/replacing your torque converter. There is no thorough way of cleaning (that I know of) all of the years/miles of sediment out of the torque converter other that cutting (machining) the converter apart. This sediment will more than likely hasten the trashing of your newly-rebuilt transmission (don't ask me how I found this out).

See if you can find a rebuilder that will rebuild YOUR original converter so that you can preserve the originality of your car. Photograph all of the existing markings so that you will be able to reproduce them. What ever you do, don't let them paint the converter (like they usually do).

If you go this route, post the name of the company that rebuilt your unit. I'm going to be traveling this path in the future.

If you look close at your lower picture it has the same line clip as his transmission, you can see the line isn't right next to the case like the top example you gave. I will have to look, I just rebuilt a 64.5 C4 and I think it has the same as his does. Also another thing to note about this 64.5 C4 is the breather tube is longer then on later production transmissions. I will try and get you a picture for reference.

Like most of these brackets with an index feature there is some slop so when you tighten down the attaching bolt they can grab and rotate with the bolt so either can be found.

Not sure what 64 1/2 trans your referring to the OP and the lower picture are from the same month and plant while the other is later but none would be referred to as a 64 1/2 period

The clip that holds the tube is in pic 5 and is different than the rubber coated j clip that holds the wire for the neutral safety switch

Here are some pics of the convertor I took before putting it back in. Tranny shop said it was still good.  Thoughts on if this is original?

Think it just might be. Not allot of them around to compare to but it doesn't look like an aftermarket or what we typically see come out of a box on a shelf at a parts store

Chris, I’m thinking original too.  Had mine rebuilt a few years back (65 Fastback, 289 with C4) and I clearly remember the white paint dab.  Can’t recall with respects to any lettering or numbers.  Most aftermarket units I see are painted.  Mine also also had a bare metal finish.

Read the shop manual and it doesn't say whether to put fluid in the torque convertor before. Should I put some fluid in it and how much?

put in about 2 quarts or slightly less.

Anyone know the finish on the vacuum modulator line clip. Painted or p/o?

not painted for sure.

Those are usually spring steel, so darkened appearance.

Yup, that's what my original part looks like with a little bit of surface rust for good measure.

Are you asking about the one that uses a transmission-engine 7/16 bolt in the upper LH corner (ID as 7B085)? If so, it's is as Charles stated, spring steel and would be a dark blue-black gun metal finish, very smooth and sort of shiny, not flat. It does not bend easy. The same for the clip on the RH side about half way down. I have not found a reference number for that one. It is shown as "clip part of trans assy".

Is there any good source for these (2) different Spring steel Tranny "J" clips???

This is close, but not exact. I could go to my friends shop and see if he has any around.

It's the identical retainer sitting on my desk. The asked for price makes me think that I could be rich. (Mine is not for sale.)

I just bought one for ten bucks on eBay. The one in that link on eBay is from a Mustang junk yard/supplier about ten minutes from me. They know their stuff and have just about anything you would need but are always pricey. My car was missing that retainer so the one I just purchased is the same as in the link. I've been on the hunt for awhile and have been unable to locate any other style retainer but that one.

This is a drawing of one type of clip that is used to retain the transmission vacuum line via a 7/16 bolt used for transmission bell housing to engine mounting. It is used on 66 thru 70 289/302 and 351W/C with C4 and FMX automatic transmissions. It is identified as "7B085" which is the complete reference on chassis drawings. The 75 MPC say to fabricate a replacement. As it does not have a valid Ford part number, I have assigned UNK52. It will appear as such in the next version of the Mustang Hardware Spreadsheets. The drawing is intended to identify the clip, and if you really get ambitious, make one.
