Re: Pan fill vs. Case fill on C4?

In the picture on the left, a C5 is on the left and a C4 is on the right.

The picture in the middle shows a C5 pan depth.

The picture on the right is a C4 pan depth.

The Bronco IIs and Ranger 4X4s with C5s had a unique pan with a deeper section near the middle.

The C4 (case fill) trans I pulled from my first 72 Torino was the numbers matching case as was the 302 that it was behind, this particular 302 is a 28 oz imbalance motor with a slightly smaller flex plate. The 302/C4 (pan fill) in my buddies 72 Torino was swapped in from a 93 Mustang GT and since Ford made all their small block v8 motors 50 oz imbalance in the early 80s (not sure of the EXACT year) and the 50 oz imbalance has a slightly larger flexplate than the older 28 oz motors.

The reason I know if this slight variation is because we pulled the trans out of his Torino because he'd lost 3rd gear and was leaking loads of fluid from the servo cover (cracked). The plan was that since the tranny that was in my car was known to be good we'd swap it into his car so that he could drive it once more. We had both trannys sitting side by side, pulledCI converter out of the old trans, drained it, refilled it, and mounted it up to my old tranny. When we pushed it all the way in it didn't feel quite right so we pulled it out and tried again. After doing this a couple times we stopped and looked at what could possibly be different (besides the obvious fill locations), we found that the newer tranny had the bellhousing bolted to the case whereas the older one had the bell bolted through the pump. The bellhousing for the newer case also happened to be wider towards the back and have a slightly wider area for the flexplate to occupy. So, just to test our theory that the bellhousings were different we unbolted the bell from the old case, crawled under the car, and tried to see if it would fit... And ya know what Dan??? IT DIDN'T FIT!!!

Those slight differences killed an entire weekends worth of work we had planned! Later this week my brother is coming down, getting both trannys, and opening up the broken one to see what exactly broke, then swapping the necessary parts so that my friend can drive his car!

torkair , the point is that you made a RULE , going by the imbalance will not tell the type of case/bell . Makes your Rule wrong

Re: Pan fill vs. Case fill on C4?

There were no factory C4s made for or used in the 90s.
The C5 started in the 80s, replacing the C4.
There are case fill and pan fill C4s with both large and small ring gears (157 & 164 tooth)

I need to know this also, I have a 65 Mustang and the C4 seems to be from the 60's has the curved vent tube and the screw in Modulator, the tag off it came back to a 65 model 289 column shift- BUT its pan fill- I am trying to do a fluid filter change but cannot trust the tag, any ideas?

Paul/Dan:
I;m looking to switch out my convertor for higher stall, my C-4/Gear vendor trans is a 70's vintage, big bell case fill.
Motor (347stroker) is neutral balanced(or imbalance i;ve heard both terms used) so, if i use the same flywheel(164 tooth) that was neutral balanced along with internals/fluidampr balancer, i don't have to be concerned about which convertor i buy,eh? Silly question, maybe, but convertors don't affect whether 28/50 or neutral balance of motor?

The flexplate is used to counter the imbalance, not the torque converter.

My '66 Shelby still has a case fill. Going on 52 years now. 44 of them spent drag racing. Never broke a case OR a 24 spline input Harvey @ PA is amazed.

Sourcing a convertor with stall approx.- 2600-2800 behind a strong 347.
Anyone recommend a particular brand, my buddy ran a TCI & had some ongoing issues, had trouble getting help from the company, Hughes seems to be a fav, any others?
Great C-4 info in this thread, Thanks to those who know their stuff
