Specifically 170 mustangs. Can someone provide me a link to detailed information on these transmissions? Would one of these be a good option for a '62 Falcon with a 170?

Hi, there is information on all of the Ford transmissions in the Ford Falcon Performance Handbook.
None are as good as the later C 4.
Good luck

Your post didn't specifically say C4 so I am going to assume you are talking about the Ford-O-Matic auto transmissions.

My 1964 Mercury Comet has the 200 cu. in. straight six (same as the 170) with the two speed Merc-O-Matic automatic which is a brother to the Ford-O-Matic. This is the only car I own and I drive it almost every single day. It has 68,400 miles and drives quite well. Although I do wish it had a third speed for highway driving.

The only thing I will tell you is to be sure and careful what transmission fluid it uses. Ford didn't switch to Type F fluid exclusively until around 1967 or so (I don't pretend to know the exact time frame so others are welcome to correct this). Before that there is a possibility that the original specification called for some proprietary fluid called Rotunda. Rotunda is Type A fluid which your local parts store does not know ever existed. Plus, Type A and Type F are NOT the same thing.

The people at Dearborn Classics explained it to me this way: If the transmission has been rebuilt, use Type F because the rebuild kit would have come with the updated parts.

Therefore, you will have to determine exactly what you are getting from your donor car in order to put the proper fluid in it. Once you have done this, Type F fluid is available in any parts store of your choosing and Type A is available through
