C6 experts..need some opinions

Ok guys, need to do a full overhaul to my c-6 transmission and about the only thing i have decided on is a oregon transmission low stall converter. or maybe there is a better converter? Looking for a good source for decent parts. the only transmissions i have ever modified are in a dodge so this is all new to me. any help would be greatly appreciated. thanks matt

Jay at Broader Performance really knows his stuff with the C6.
If you buy from him he'll give you tech. assistance on your rebuild including some tips.

some cheap small parts can make a big improvement like the F servo apply lever that goes inside the unit, it is the lever that apply the band.
Good for a firm 2nd gear shift.
The servo can be changed to the R servo wich some kits have different springs for shift quality, but that is over $100 and nobnody want to spend that kinda money.
Like spending $600 for a billet low stall conv, they are out there but dont want to spend the money.
At least the C-6 dont need much money to do the job, very sturdy unit OEM



If I added up what it cost to do my C-6 it would be more than I can buy a crew cab dually for. that is parts alone! I built the unit myself so I saved big time there.

But my unit works flawless under any type of service I need from it.

$115 HD Low stall C6 T/C with the large bearing size. This is probably the one I'm going with in my Crew Cab project. I've owned a C6-equipped truck with a BD Converter for about a week, and it's something fierce to drive! Almost like being in a manual truck. That's the first HD torque converter I've ever owned/driven, and I'm sold for life now. I think I'm going with Oregon Performance Transmission's HD Low Stall unit because as Javier said, I'm not so sure I want to fork out a ton of dough for another BD unit.

You can also get a 'gear reduction' gear set for a C6 with a 10% lower first and 5% lower second gear, $216. This is another nice option for C6 owners. I think this combined with a HD low-stall converter would be sweet.

Here's the text off the site:

"Low gear planetary kit for the Ford C-6 transmission. This set will work for all years. This kit will lower your 1st gear ratio to 2.71 from your stock 2.46. Second gear will be lowered to 1.53 from 1.46. The kit comes with a new steel, 6 pinion planetary, hub, Torrington bearing, ring gear, sun gear, and sun shell. This kit will increase your acceleration without changing your rear-end gears."

That's probably the E4OD gear set swap correct?

I believe so. I don't have any personal experience with it

4 pinion early low gear and 6 pinion late low gear are from the E40D.
Thrust washers are the early kits, now they come torrington roller bearing
and last I checked they are not cheap.

The following are the links and shopping list of parts I used on my build in 2007.

In addition I mounted the largest external trans cooler I could find at a reasonable price. It's rated @ 30,000gvw cooler.
I did alot of research and found the following parts were the best bang for the buck and longevity for the tranny. If your doing it yourself just take your time and save your old parts(I used an old steel as a shim in one of the drums). Do one step at a time ex:disassembly one night laying out all the parts in order as they are removed, make a parts list, clean for reassembly, rebuild valve body next night, ect..
A manual is a must (you'll see it on my list). You may want a local shop to compress the spring in the one drum, it takes a tool to do it and without the tool you take a chance of ruining a new drum. Don't forget to soak your clutch discs for 1/2 hour before assembly.

The second link is for the drums incase yours are wiped like mine were. Plus using these drums give you another clutch disc.

Changing the gear set only affects 1st and 2nd. 3rd stays the same.

I put the wide ratio set in mine when I rebuilt the C6 and if I was to do it again I wouldn't bother.

If your hauling really heavy loads I could see it being worth it.

Ok, Precision, low-stall torque converter, R Servo (springs) assembly, forward valve body kit from Transgo, steel planetaries and sun gear.. .....I asked Precision how much slip (percentage wise) that torque converter does slip....he seemed to think about 5%. He was not very convincing...but hey; had to make a decision an the Precison is good. (so goes the word on the street at least).

The Precision converter that BTS uses is a different company. Not to be confused with Precision of New Hampton.

Which one of those converters is the better choice?
