So, in my 79 f100 i have the original C-6. It leaks a little and will not shift into drive untill it warms up. Also heard this was a common problem due to some seal that shrinks or something. How much would it typiccaly cost to rebuild a c-6, if i do it myself vs. dropping the truck off and letting a garage do it? Just a stock rebuild, nothing fancy, no shift kit.....also, if i decided to paint the tranny...what color would ford have done...i was thinking just gloss black

 

I don't believe c-6's were ever painted. Rebuilds at a shop are around 700.00 give or take on the shop. At least in Sacramento. If you do it yourself I have seen rebuild kits for under 300.00 without the TC.

 

whereever you are located these trucks are old dont exspect it cheap itll be up around 600 or 700 i do agree with co425 a rebuild kit is about 300 or 400.

 

Had my C6 rebuilt a couple of months ago. Cleaned the case, freshened up the TC, new soft parts, kevlar bands, B&M shift kit, all hard parts checked out, dyno'd to check the shift points, and hit with a coat of black paint. About a half-day's labor and $600 out the door. I had to drop the tranny myself...which was an adventure without a transmission jack and a fancy lift. A floor jack, a piece of scrap 4x4, and a C6 precariously perched on top. Not the most stable of configurations.

The best part was getting my wife to help lift the 200-lb sucker into the back of her yuppie Nissan Murano!

 

ha jlj6t thats funny yuppie nissan murano but those c6 are nice and id bet you could get a great rebuild i mean total makeover rebuild for around 1000 am i right?

 

I'm sure. I actually budgeted for $1K to do mine... I'd consider mine about as "total makeover" as you can get, short of putting a brand new TC on it. They checked out mine (turns out the PO had already put a higher-stall TC on it), flushed it, and said it was good to go. Unless I was going to race it, they didn't recommend I buy a new TC. Refreshing to get that kind of customer service...they could have just as easily taken more of my money to give me something I didn't need/want.

Performance Torque Converters in Muscle Shoals, AL, if anyone is curious. They specialize in racing applications, but were more than happy to do business with me. Great group there. Performance Torque Converters - Performance Torque Converters

 

Shoot...not cheap????? How much cheaper do you want? The C6 is practially the easiest trans to rebuild. Have you priced out getting a newer trans rebuilt lately, you're looking at about double what a C6 costs. My last AOD and E4OD's were all between 12-1600 for stock rebuilds. Anyway, a C6 will run you between $6-800 for a stock rebuild at a shop, and would be about $300 in parts if you decide to tackle it.

 

Whatever you end up doing, don't forget to flush the lines and cooler out real good before starting it. You don't want any of the old crap going right back into your new rebuild.

The only tool you HAVE to have is a Clutch Spring compressor from the above site #C6T $50 the other stuff just makes it easier. You are not going to pull the clutches apart without this tool.
It is pretty easy to take a working transmission that needs a rebuild and put a kit in, the hard part is when it is not working right.

 

I had mine done by a local transmission specialty shop - it would not shift into 1st or 3rd - I was stuck in 2nd all the time. They opened it up and...well...it was in bad shape. I cannot remember everything they did, but I virtually have a new transmission. Total bill was about $1400.

 

About 300$ for a stock build like everybody has said. Did mine last winter with ZERO prior experience and it was a breeeeeeze. By far the hardest part was dropping it and puting it back in as people have said, by myself, and with a floor jack. You can make a clutch spring compressor with 4 bolts, about 10 nuts, and one triangular piece of steel with holes, a barn door hinge works well. No drilling or welding required if you plan it out right.

Get an instructional DVD for your trans though, look up BadShoe productions. Nothing fancy but the guy knows every little in and out, and has alot of tips.

Go for it, and goodluck, AleX

 

i got an estimate today on mine and he said complete rebuild would be $15-1700!!! And he is the only tranny shop in town besides AAMCO. I don't know why his price is so high.

 

Well, ya answered your own wonderment right there... Some folks may not like AAMCO (like me) so he's the only other game in town.

Have you considered a reman through Autozone or Oreilly? What about a mail order C6 through Jegs, Summit, or Performance Automatic???

 

Rrrreally? Haha, think that up there ^ might have a little somethin to do with it.
