In your opinion, what's the best transmission Ford made?

Both automatic and manual.

 

The C6 is bullet proof.

 

the c-6 is a great tranny

 

C6, or E4OD.. The early E4ODs had some problems, but after they fixed them they were great..

 

I abused several C6's and never had a problem. I sure cannot say that for the C4.

 

I too like the C-6 a/t

As for manuals; T-18 in a truck

Top Loader in a car

 

I don't really like the E4OD because of it's inability to coast. Torque converter gears 1 and 2, direct drive 3 and 4...you get the idea...

Other that small snaggle, it's a great tranny. Mine's lasted 140000 and still going strong.

 

C-6 for automatic
ZF 5-Speed (the heavy duty one behind a 460) for manual.

Mine would unlock the TC in third, but you had to me movin pretty slow.

 

C6 all the way.

 

The only hills that I can coast on around here are on roads where I'm either in 4th or OD...or 1st.

 

The original AOD (no computers on it ) and for stickshifts, I can't decide between the T-5 tranny or the ol' 4-speed like I learned on in the '66 Mustang we used to have...

 

c4 is pretty good, my daily driver has one and it shifts nice and firm, but I have to say the c6. Strong, good engine braking, and lasts forever. As for a manual, though, I'd have to say the NP-435. Very strong, last for a while as long as you keep some sort of oil in them, and a good range of gears to select from.

 

I had two C4's go bad due to clutch problems. I would consider this a very weak (almost junk) transmission. Definately not the best.

 

Maybe the question should be refined to "used" vs. "made". Probably the C-6 was the best all around transmission "used", it is not that heavy, but, could stand up to 1 ton use.

I did not know much at all about the NP435, but, after using and researching them, I would count that as the next best after the C-6.
