salvaged automatic transmission out of 66 f250. was told it was a c6, but not sure how reliable the source. Read the article in 'tech' forum and appears to fit description of a c6. Trying to confirm for my own interested. Checked various web sites, and reviewed shop manuals but not helpful. Called local trans shop as i was removing tranny and told not familiar with early model tansmissions. Can anyone refer me a web site, manual, etc. I would like to know what it is I purchased, whether I wasted $125. If confirmed it is a c6, my next post will be w/ local chapter regarding transmission rebuild referral.

any input would be apprecited

thanx

Run a search using google as well, if this doesn't help.

Frankly, If that transmission is original to the truck, I doubt it is a C-6. Just my initial thoughts, though.

 

Thanks banjopicker. Checked out the web site referrals. Still unble to determine. Unfortunately, think I am now saddled w/ a cruisematic. The code on side of transmission is 'RF-CBTP' and under this # is 7AO 40. this may turn out to be expensive lesson.

thanx again,
dave

 

The COM is not a bad transmission, just not the best. C-6 is by far the better choice, but if the COM is good, why not put it in and run it till it dies? You can then put in the C-6 you will have obtained and rebuilt by then.

 

Thanks banjopicker, I will do that. It may give me alot of good use and it won't be a total loss.

In addition, the donor truck had power steering so I removed the steering column, including the shifting lever and indicator. I was wondering if anyone knows can I replace the indicator and use the same column when I change to the C-6.

If anyone is interested, no I do not want to buy beach front property in Montana.

thanx,
dave

 

URGENT! IF THAT TRUCK HAD FACTORY POWER STEERING, GO BACK AND GET THE BOX!
ALSO GET THE PS BRACKETS FOR THE ENGINE (if it is the same.)
That is, if you want power steering!
This will be long.
'65 and '66, Ford used a Bendix power steering box. It is 2 inches shorter than the Ford power steering box used '67 or so - '79. That Bendix box is HARD TO FIND, and is worth a lot as a core even if it isn't useable.
I just converted my '66 F-100 to PS this summer, and I researched everything first, and got it right the first time. Here is part of an article I did on this subject:
Brackets: Since you have the FE family engine, you can use the power steering pump brackets, pump and crank pulley from any FE engine, in any Ford car or truck. The FE was phased out of trucks in '76; not sure about the cars but I think it was the same year. There were several types of bracket setups, so try to get a complete set of brackets from the same motor or vehicle. The different setups don't mix and match, but as long as they are a complete set, you can put them on any FE engine. There are usually 3 pieces to the earlier sets, and 2 to the later sets. Don't forget to pull the crank pulley and the crankshaft dampener while you are at it. There are two variations of the damper, 4 mounting holes for the pulleys and three mount holes. Don't make the same mistake I did, and get a 3-hole P/S pulley for a 4 hole damper!

Pump: This one is pretty universal. It to can come from any car or truck, but you may have to make several trips to the parts store to get the correct hoses and fittings. If you can get it off the same vehicle you get the brackets from, get the hoses as well, even if the pump and hoses are bad. You can use the pump for a match up, and a core. Same for the hoses.

So much for the easy part.

Power Steering Gearbox: There was only one type used on the '65 and '66 - the Bendix made box. The Bendix box is very hard to find, is weak, prone to frequent failure, and very expensive to have remanufactured. I found several companies who would sell me a remanufactured one without a core, but they wanted about $600 by the time all was said and done. (Note: This Bendix box was only used on Ford trucks, not on any other vehicle. They used it on F-100s up to '69, but used it less and less as Ford phased in their proprietary box.) Also, note that the Bendix box has the same dimensions as the manual gearbox. This is why the auto and the manual transmission columns are the same length '65 and '66.
Ford started using their used their own P/S box in '67, and used it exclusively from '69 to '79. It is robust and heavy duty, but is two inches longer than the Bendix. The Ford box will bolt right up to all '65 and '66s, but it will interfere with the stock steering column. See below on steering columns.

Steering column:
The steering column length is the same for manual and auto transmissions with or without poweer steering '65 and '66. If you wish to use your stock column, you will need to
a. Cut it about 2.5 inches shorter (then weld the rag joint coupler back on if an auto column, or re-build the shifter mechanism if standard AND then weld the coupler joint back on) to accomodate the longer Ford made P/S gearbox; or
b. Use the Bendix made P/S gearbox.

If you use the Ford P/S gearbox, you can use a '67 to '79 steering column from a truck with P/S. You will need to relocate the dash support bracket on the column (cut two spot welds then re-weld in the correct position for the dash in the '66), and fiddle with the wiring to get it right, but otherwise it is a bolt in. You can even use a tilt column from '78 and '79 trucks.
Unfortunately, there were VERY few trucks made with P/S and a three on the tree column. I know. I have been looking for one for about five years now.

So, if you have a 3 on the tree, you will find it best to put in a '67 or later column and put your shifter on the floor.

In summary:
Bendix Box:
Advantages: Exact bolt in, no changes to steering column.
Disadvantages: High cost, short service life.

Ford Box:
Advantages: Inexpensive, reliable, durable, easily available.
Disavantages; Requires steering column alterations

Options using the Ford P/S box: (Remember, these columns must come from a truck with power steering!)
1. Manual transmission, column shift:
a. Get really really lucky and find a good '67 or later tree-shifted P/S column - except that now my Houdini hypnotizing powers will now overtake you and you will sell it to me. Proceed next to option "B".
b. Shorten shift column - very hard to do correctly.
c. Use '67 or later column for floor shifted transmission. Put shifter on the floor.
2. Manual transmission, floor shift - use '67 or later column for floor shifted transmission. (You could also use a tree-shift column, and just disconnect the linkages.)

3. Auto transmission: Use an automatic transmission column from a '67 or later truck.

Hope this isn't too confusing, and that it helps!

 

Thanks banjopicker, I can't thank you enough for the info

It sound as if it would be easiest go back and retreive the Bendix. However, I had already salvaged a steering unit, and column out of 75 truck. I have been trying to figure out a way to modify the donor and original column because of the dash mounting issue. The donor column's mount is somewhat flat and appears it would require spacers>thought perhaps I could swap mounts.

What a dilemma. I may go and get the bendix, I tend to like having options. So I have few extra parts.

Again, thank you

 

No longer faced with dilemma. I went and retreived the Bendix. Also took anything else remotely connected to the p/s, including brackets and pulleys.

I will keep an eye out for a good 67 or later 'tree shifted' p/s column.

thanx again!
