The transmisions are still the same. They just use a non lockup converter. same valve bodies, drums etc. Torn apart more than a dozen and they were all identical inside. Only differences would be truck or non truck for the most part... Need a lockup valve body?

The transmissions ARE all lockup. 20 years later the converters either dont work or never had the clutch installed but the transmssions themselves were ALL lockup spec transmissions.

Thats what it looks like. Ive never seen a C5 that didnt have the typical C5 valve body. It looks like the factories just used a different converter when they wanted a lockup setup. Its just a centrifugal clutch that isnt actually a lockup converter like you normally think of with electronic controls and solenoids to control converter lockup . It was a stopgap measure until Ford came up with an actual lockup transmission .

did they have the usual C5 valve body with the extra control body section and deep pan?

Yes 1 did ,it was from an 82 6 cylinder F100. It was the small case fill type.
The other was a pan fill type case from V8 ,had E2 casting code. It was all C4 ,valvebody as well. It had the fine thread front band adjuster,case oil hole #9 and the C5 sun gear with the bigger holes. This one had no converter but bellhousing was same depth as C4.
Seems to be few variations of C5 here then.

I had a C5 from a 2.3 Ranger that was non lockup converter and it had an additional thin pressure plate in the high gear drum so that it only used 3 clutches.

The 6 cyl one i got has a thin wave plate but still had 4 clutches but had a .140" top pressure plate to make up the difference.

All the C5's i have had did have the lockup style valve body. I have installed shift kits in these valve bodies and they worked just fine. It is the converter that is lockup or not. The 82 i have right now was out of a Cougar V6 and it was a non lockup converter. I used that converter behind the 306 for a yr. it worked pretty good as i got maybe 500 more rpm stall.
