Used wrong transmission fluid

[hmills]

Well guys my son and I (father son project you know) did a complete flush on ole blue. We did it just just as Barry and Qman suggested Here are the steps:
1. drain and clean pan, replace filter
2. add fluid (Type F this time) and leave the funnel in place so you can add more fluid (see step 6)
3. there are two 3/8" lines going in/out at the bottom of the radiator - disconnect one of them.
4. Have your son watch the line and the fitting coming out of the radiator while you turn on the truck. Have him identify which way the fluid is flowing.
5. affix a clear hose (i used about 3 feet of 5/8") to the point that the fluid is flowing out of.
6. turn on the truck and have your son fill up an empty quart container while you add a new quart of fluid. Make sure he watches the site line on the side of the quart container and tells you when it starts to get full. Give him an empty quart container and go get another new quart of Type F.
7. Repeat step 6 about 12 - 15 times until the fluid in the clear tube is nice and red. I ran thru the gears (with parking brake on and foot firmly on the brake) several times during the middle of the process.
8. stop the engine, clean up a bit and top off the fluid level, put away your tools and take her for a spin.
Guess what. she ran great and Chris (15 year old) got to drive her for the first time. Man oh man, now that was a good day! thanks for the tips guys you just helped a father/son team take one more step to getting ole blue on the road.

The biggest difference between the Type F and Dex/Mercon is the Anti-Sudsing Agent. If you put Type F where it calls for Dex/Mercon instead of having a Hydrostatic Transmission you'd have a Foaming/Suds making Contraption!
According to FORD of course I'd never tried it before...

I don't know that it's all that critical, I've used both in various trannies over the years with no ill effects. My '69 is a good example, the tranny pan gasket leaks pretty bad. I've bought a filter kit, but haven't gotten around to putting it in. When I bought the truck the I put in a bunch of type F because the id plate says it has a C-4 in it. When I changed the modulator I discovered it was a C-6 so I switched to Dextron because I read that C-6s use Dex. (Dontcha love Chilton?) Since then I've heard otherwise, so I've been adding F when it needs it. Doesn't seem to care either way, shifts and works great. This may be wrong, but it's my experience anyway.

Dextron is better. Won't hurt FORD tranny.

I got --Dex in my C4 sin of all sins. It works fine. Oh my. A 67 C4.
Go figure
