FordFETruck Posted June 22 Author Share Posted June 22 Gary honestly this is the third auto trans rebuild I'm going through and the second C6, at this point I'd much rather do the transmission than the engine I find it a lot more enjoyable actually. Made a fair amount of progress today. I got the forward drum disassembled, cleaned, new seals and clutches installed and clearances checked. I removed the wave plate and replaced it with an extra steel that came in the rebuild kit to get the clutch pack clearance more in check. It was at the max limit with the wave plate at .046" and with the steel plate it was at .039" so I went with it, it'll shift a little firmer into gear with the wave plate out. Got the reverse/high drum disassembled, cleaned and reassembled and noticed it only had 10 springs instead of the 18 total it could have. I know this is a trick to make reverse engage less harshly, not sure if somebody actually has been in this transmission before and did that or if Ford themselves were doing that to soften reverse engagement, either way it's all together and in a bag and both drums air check great. The governor was pretty sticky and explains why in cold weather the transmission wouldn't always downshift to first until you step on the gas to take off. I cleaned and polished the valves, cleaned it all again, lubricated everything with silicone spray and it works like butter now so that should fix that issue. Tomorrow I'm going to pressure wash the case and some other parts I need to clean up along with the engine bay. I've been on vacation all week and sick as a dog the whole time, but I guess its better than being at work sick. In the picture with the springs there's actually 10 installed but I only had 9 showing for the pic, yes I had to take that back apart after the fact. I also cleaned up the intermediate band surface area with some old sandpaper and diesel in the parts washer, looks almost new. Link to comment Share on other sites More sharing options...

Bummer that you've been ill, especially on vacation, but apparently you are well now? What kind of parts washer do you have? How big is it?

What kind of parts washer do you have? How big is it? Getting better but my voice is still a bit messed up and throat still a little sore. I have one of those smaller parts washers like harbor freight sells. Works pretty well for how compact it is. Link to comment Share on other sites More sharing options...
FordFETruck Posted June 23 Author Share Posted June 23 Getting better but my voice is still a bit messed up and throat still a little sore. I have one of those smaller parts washers like harbor freight sells. Works pretty well for how compact it is. Alright today I pressure washed the transmission case, pressure washed the engine pulleys, engine bay, headers, gave the headers a spray of SEM rust mort, will likely paint them tomorrow. I got the shift shaft seal changed in the case, the cooler line adapter fittings resealed, all of the sealing rings installed. I wound up changing the bushings in the pump stator that support the input shaft, the one on the converter side was pretty sloppy. That was 2 hours of pure fun. Got them cut,chiseled out, pressed in new bushings and one fit great the other I had to take the kingpin reamer to and finish hone it with the brake hone, fits perfectly now though. It's all going to go together tomorrow other than the pump, I am still waiting on my pump gears to arrive Monday. The new pump converter bushing is teflon coated, I test fit it on the new converter after pressing it in and it fits great and turns so smooth and slick with that coating it makes me wonder why all of the bushings aren't teflon coated. I also changed the tailshaft bushing and seal. Link to comment Share on other sites More sharing options...

I have to wonder how many people really know how to work on something that used to be as ubiquitous as the C6 in this day and age of 14 speed electronically controlled automatics? At any rate, it looks like your truck will be back (better than ever!) very soon. Hope you're feeling better! 🙂 Link to comment Share on other sites More sharing options...

My dad went to automatic transmission school in the 70's and was trained on the C6. I did the first C6 with him for his car about 10 years ago but I haven't gotten any help other than him looking up some specs in the book when my hands were dirty. I definitely don't rush anything when it comes to the transmission and I get everything as clean as possible and bag it immediately. Still not feeling 100% but pretty close to it, just a bit of congestion left now. Link to comment Share on other sites More sharing options...

We have COVID making the rounds here, again, and getting over it takes a while. Link to comment Share on other sites More sharing options...

We have COVID making the rounds here, again, and getting over it takes a while. I sure hope it'll work nicely I'm not sure what I got, my coworker was over helping me do some drywall work on the 15th, I ran into a little bit of mold and tore some drywall out in the garage office, I started coughing immediately from it, mixed up some bleach and water pretty strong and sprayed it, the fumes made me feel pretty crappy and I felt ill ever since. I don't think I really got sick from the mold or bleach but I think it brought it on as my coworker and his whole family have had the same stuff I had, he got tested and it wasn't covid, but it sure is nasty stuff whatever it is. The first couple days I had a fever and it felt like a chemical burn down into my lungs which may have also been from the bleach a bit, but I got about 3 hours of sleep total the 15th through the 18th, and had a really sore throat and bad voice the rest of the time, followed by a sinus infection type deal later in the week. I feel pretty much back to normal today, just in time to go back to work tomorrow Link to comment Share on other sites More sharing options...
