well I have been sitting on these pics for a bit so I figured I would let em fly... its new debut will be at ts on the dyno, in hopes of somewhere around 600+ on fuel only w/single charger, Im not going to hook due to the limited tuning time I will have on the truck but hopefully she will due good on the dyno.... the cookie monster will be an absolute animal when it rolls back outta the shop.. there will be more pics as progress comes along LOL :rockwoot:

the one is me gettin that PITA FAN OFF UGHHH:bang

a 6? from Trusted, and some 2XX stick from a well known company.. dont want to release everything yet.. it will be sweet though
 
Gotcha, sounds great! I know the 200's and 66 from River City Diesel on my 06 have made 600. Its nice to see folks out making good numbers with the "6-leakers"!
 
man there are some 5R110 haters over on the NATION, they seem to be pro 4r100, its interesting. and I hope that I dont have this kinda problem.

It isn't the tranny that is the issue it is the computer that controls it. There is one major difference with the trucks you just talked about and what you are planning on doing with your truck, HIGH AND LOW RANGE. They use different shifting tables and different reasons for shifting. In super simple terms, in high range it can be programmed to shift on rpms for racing, you cannot use rpms in low range. You also can't get the TC to lock up right in low range. So then you will be trying the lockup button idea and that will limp the tranny. Then you will try to put the wire behind the glove box to not let the truck know that it is in low range. Then it will shift great for about 200 ft, then the truck will figure out through the tires are spinning to slow for high range and then limp the tranny.

I have had 3 different transmissions in my truck and somewhere in the neighborhood of 5 different convertors in the last two years. I have had 3 different vendors trying to get the programming right. Could never get the tranny shifting right.

So if you want to pull, don't use a 5R. If you want to drag race the 5R is a great transmission.
 
Most of the guys on PSN are die hard 7.3 fans. Not saying anything against them, but the 7.3 and the 5r110 will always be the best in their minds.
 
Tim, I am the 5R hater.

I love it for a daily driver and for drag racing.

I just hate it for sled pulling, he is trying to build a sled puller so that it why I spoke up. I am not trying to burst anyones bubble. I know of about 4 trucks that are trying to be full time pullers and none can get the tranny to work right. I am just trying to save the OP some time, money and frustration. The tranny is pretty sound mecahnically to well into the 600+ hp range pulling. The ***** is you can't get it to shift right. The tranny is just to smart and will do whatever it wants on its own. No matter where the shifing lever it put. If Ford would have put an RPM table for shifting in low range then we probably wouldn't be having this discussion. The tranny worked great for pulling when my truck was around the 550 hp range. Once we got the truck into what was roughly 600+ range all these shifting issues started showing their ugly head. Then when we took it to a pretty similar build as Rednecks then hard parts starting breaking every pull. I never made one pull last year without breaking something in the drive train. This year I shouldn't break anything, the pulling truck won't have a 5R anymore. Life should be way better!!
 
well Im glad I know it now LUBE, Im just stilll puzzled about this whole damn shifting tables. but I understand what your saying totally, I guess we will see what happens!
 
Though I have never had one bit of problem with my suncoast and the 5r110 I know a few 6l pullers locally that are switching to a 4r100 for next year. I dont know if its a tunning thing or what.I just know they are switching I wonder if a PCS controller on a 5r110 would help.

Sonic you live in Ohio/Indina...Call Mike Hallas of HAllas performance. He builds alot of pullers in the area and also was in Diesel power challege. Pm if you want his number. He might shed light on this and maybe also build you a stout trans
 
Might as well say it on both sites:
Here from the resident Ford tranny guru:

The 2-3 is a swap shift. This is a special catagory of difficult shift. I believe Ford is the only trans maker in the world that still does swap shifts. Others have put swap shift transmissions in production and then replaced them within a few years. To make a swap shift the TorqShift needs to release the OD clutch to downshift the OD gearset while applying the intermediate clutch to upshift the Simpson planetary gearset. This is an upshift and a downshift occuring at the same time in the same trans. From my experience these two shifts MUST complete within 30 milliseconds of each other or it's going to feel awful. If the OD releases too soon the engine speed will flare. The amount of flare is dependant on how much sooner it completes. If it completes before the intermediate has enough capacity the trans goes back to first gear! Then it has to make a 1-3 shift. A few WOT 1-3 shifts means the trans comes out to replace the intermediate clutch. Been there, done that. If the OD releases after the intermediate comes on you end up in 4th gear (1.09:1 ratio) then downshift back to third gear (1.54:1 ratio.) Either way it's really bad.

You start having some 2 to 4th shifts and causing you to loose alot of rpms and you will hate the 5R just like I do.

After reading this I would think that you should be able to understand why many less perameters in the low range shifting table will get your tranny to end up with shifting problems.
