Well I've been working on my 69 again and trying to fix some of my leaks. I started with the tranny - replacing the shift shaft seal, output shaft seal, new cooler and lines, the old stuff is pretty banged up. Anyway, I pulled the pan and noticed that in the fluid and on the bottom of the pan there are alot of metallic particles. Not metal pieces but very very small particles, its like tiny glitter in the fluid. Is this to be expected? The tranny has been slipping alot on the 2->3 shift since I got my new motor in, if I'm on it a little I let up to get it to engage into 3rd. The 1->2 shift is pretty sharp. I was planning on adjusting the bands and figured this might solve the slipping problem. Is this correct or do you think I've got bigger problems to come with the tranny? I don't want to spend the time doing what I have planned only to end up haveing to pull the tranny out and get it rebuilt. What do you guys think? Any advice would be great. I'm hoping some of you have been down this road already.Thanks,
Brock

It's common to see this at the bottom of the pan. As the tranny wears, friction material and little bits of steel precipitate down.Tightening the bands will help, but you can't put the material back without rebuilding, unfortunately. ------------------

So how do I know when it's time to rebuild it? See if it still slips after adjusting the bands? Wait until someting fails? As far as I know the tranny is stock with a shift kit. My motor is a moderatly built 351w with a estimated hp in the range of 350 to 400. How long will a basically stock c4 hold together with this motor? The car is a street only car.Thanks for the help,
Brock

Let's go a little further. I saw a while back that someone said c-4's were rather easy to rebuild. What do you need exactly? Alot small tools? micrometers? I have an extra c4 that I have considered playing with. pointers anyone? Mike

Bands have only non metalic riction material. Adjusting the band will improve the 1-2 shift only. All automaitc transmissions wear by their nature and it is normal to find particles in the pan from clutch wear during a trans service.  ------------------

All you need for special tools are snap-ring pliers, an inch-pound torque wrench and a good manual {such as a Ford shop manual}. Clean each part as you remove them, and lay the parts out in an 'exploded view' order on a bench. Auto trannys stay relatively clean as a rule, so they are easy to get really clean for assembly. Use type F ATF as assembly lube. Follow all the assembly instructions in the Ford manual to the letter and you'll do just fine. ------------------

A rebuild kit is about $100, by if it doesn't slip you could get by with changing a few seals.------------------

Thanks for the info guys. I've decided just to rebuild the tranny myself. In other posts people have said that the C4 is one of the more simpiler trannys to rebuild. I've got the shop manuals and am gonna get the Haynes Ford tranny book and go for it. Does anyone have any recommendations for quality rebuild kits? I've been looking at the TCI kit which is supposed to contain everything needed to rebuild the tranny. Any thoughts on this one? Also, any suggestions, tips, etc. for someone tackling this for their first time would be great.Thanks,
Brock

Where did you find your rebuild kit at and what kind of torque converter did you look at? Mike

Get a set of the reprinted Ford shop manuals from National Parts Depot or Mustangs Plus. {surprisingly, Osborn doesn't sell them.} They are worth their weight in gold. I bought a Haynes manual for my wife's Probe recently. What a waste of money that was! ------------------

I think Alex has said Trans-go is one of the best sources for Ford auto trans kits. http://www.pro-built.net/products/transgo.html#ford ------------------

That is correct Steve. Trans=Go makes the most complete and highest quality shift kits. ------------------
