The C4 in my car is from a 1980 Granada that was at P&P. I pulled it out, cleaned it real good, changed the front and rear seal, and installed it with a 164T 302 flexplate because the Granada had one that size. It didnt take too long to realize the column shift linkage parts in my previously 6cyl Comet were not going to play nice with the 302 that was hanging in there when I bought it. I decided to install a Granada shift cable since the transmission was set up for that on one end, I just had to fab a bracket for the other end and attach it to the column lever under the hood. The transmission came with a coat of silver paint, and was very clean inside which made me think it might have been re-built. Well, it worked flawlessly for about 200 miles...then gradually developed a 2-3 flare. It also started to leak from the shift lever, speedo cable housing, and pan.....because I suck at c4 pans. I took a 2nd run at the pan, and got it to quit. More recently I put in an H servo, shift kit, shift lever seal, and green stripe modulator. The flare just feels like a flare with a shift kit....lol....a flare that didnt care....a flare that wants to toy with me and taunt me. I have also been chasing drive train vibrations since the car left my backyard for the first time, in 2016. This year I finally got my pinion angle sorted out, and the driveshaft balanced....so the vibration? It finally dawned on me to put it in N at 70 and, and, and it was soooo smooth! In the interest of preserving my engine bearings, that c4 is coming out and the TC is going away. I decided that since all the c4 rubber seals crapped on me, maybe the one on the direct drum pooped and my flare is from that? It is going to come out and get torn down. I have watched videos of guys completely tearing them apart in less than 10 minutes, so I have convinced myself I need to try it. I need to hunt down appropriate literature, drop that junkyard special out of there, and rebuild my first automatic. Roger, if you read this, your courage drives me onward sir! What would help me to not be stupid is some education on the millions of repair kits, kinds of clutches, bands, blah, blah. This thing basically works perfect except for the flare. I probably am feeding it about 320Hp and will not run more than street tires. Do I need red clutches? Are there clutches, kits, suppliers, and things to avoid? What determines the continued use of type F fluid?
