Transmission ID & Parking Brake ??'s

Tracing out the cable to the speedometer, I found that it was disconnected under the truck, just kind of hanging there. I'm not sure if it's even the correct cable- I don't know what transmission this is for sure-

Sorry about the bad pic, cell phone camera was all I had handy... If it helps, the lettering on the side reads-

rfg8tp

7a040a

w2

I know that the transmission isn't original- I suspect it's from the 70's sometime.

Also- The parking brake handle in the cab isn't connected to the cable... It APPEARS that everything under the truck is intact, just not connected to the handle. Of course there is nothing in the service manual about it- at least not that I can find.

How do I remove the handle and replace the cable???

Thanks!

-Andrew

It's impossible to answer your questions since you made no mention of what your truck is.

What year/series is it? Is it 2WD or 4WD, 3 speed or 4 speed? What is the wheelbase?

The 7A040 number you posted is the ID number marked on the extension housing, but the RF G8TP prefix makes no sense.

The following makes sense, so it could be: C8TP-7A040-A (C instead of G), or D8TP-7A039-A (D instead of G).

It's a '66 F-100, 2wd. BUT, the transmission/engine have been replaced- When it was built it was a manual. It still has a 352 in it, though it appears to be a later one (Blue valve covers w/Power by ford embossing). To be honest, I don't know ANYTHING more about the transmission...

I'll have to try to get a better look at the numbers, I was at a BAD angle when I was climbing around underneath checking out the brakes...

Just what do I need to find on there to ID it? Where will I find it?

Thanks

I got down underneath for a better look... It is a c-6 I think- 17 bolts on the pan... You were correct,ND, the number on it was C8TP-7A040-A, there was some 'crud' on the C that made it look like a G from the angle I was at.

That would be a 1968 Transmission, right?

Now I need to get a new speedometer cable for it- The old one that's dangling there was for whatever transmission used to be in there- And, Of course, Won't fit the new transmission. Hopefully that's all I need to get the speedometer functional!

I got the parking brakes working, too- Just a matter of reconnecting them- the cable was disconnected at the handle. I had to take it all apart to see how it went together- Once I saw it, it was EASY!

From the looks of the speedo driven gear, you will need that too, available from Ford for less than 4 bucks. 16-21 toothed gears are available, count the number of teeth on the original, get the same one.

The original 1965/66 cable w/a 3 speed manual is 64.80" long. With a swapped in C6 trans, I dunno how long a cable you'll need.

1968/72 F100/250 w/a C6 speedo cable (C7TZ-17260-AB): 75.42" long. This same cable was also used in 1967 F100/250's w/the MX Cruise-O.

C8TP-7A040-A = C8TZ-7A039-A .. C6 Extension Housing / 1968 F100/350 & 1969 F100/350 before serial number F33,001.

Thanks, ND... Helpful as usual!

That gear is from the OLD manual transmission- It was just hanging there. Apparently, when they swapped out the engine/transmission, they didn't care if they had a speedometer...

I found the cable at AutoZone, for $15, and now have a functional speedometer! The odometer doesn't seem to be moving, though- So I guess my truck has 70,300 miles on it for life now.

And, despite the fact that the parts counter guy at autozone assured me that there was no such thing as a 302 Ford engine- I MUST mean a 351- I also have a functional engine temp gauge as well... The engine has an Edelbrock intake manifold- So the temp sensor for the 352 was a different size, but we figured out which one I needed, eventually- DESPITE the help I was given by the autozone staff

This is the one that I used-

Pioneer/Speedometer Cable (CA-3004) | 1970 Ford F100 1/2 ton P/U 2WD 8 Cylinders H 6.4L 2BL OHV | AutoZone.com

I had them look up a 1970 F100, w/ Auto. This is the part that it found. The cross reference matched the # that N.D. gave me- so I gave it a shot...

If the bell housing is round, it's for a 360-390 engine. Will not bolt up to a 351C. You need a Trans from a 300/302/351. That type bell housing will be about the same diameter but flat on top instead of completely round.

This a picture of an AOD, but same bell housing pattern you need.

It's an FE. I believe but not totally sure that the 462 was a taller like a 460 or 7.3 but slightly angled at the top.
