Torque converter replacement.
Okay, just changed out the torque converter and it was way easier than I thought it was going to be. You do not have to take the motor apart at all you can get to the top bellhousing bolts with a series of extensions and a swivel. Then I was able to disconnect both drive shafts and the...- Fanatic1074

Torque converter replacement.
In my experience the service manuals have you doing too much. I do have the manual. Just figured someone might have some shortcuts. Thanks anyway.- Fanatic1074

Torque converter replacement.
I'm about to swap out my torque converter on my 03 5.4 4x4 4r70w and was hoping someone could point me in the direction of a good walk through. I just don't want to be taking apart more than is needed. I would really appreciate the help. Thanks!- Fanatic1074

Transmission problem
145k on the truck. Original trans. So what happened to the trans cooler ? Plug up? I can use my mityvac and run some fluid through it to check flow before I put the radiator back in Sent from my SCH-I535 using Tapatalk 2- Fanatic1074

5.4 Motor rebuild help.
I can get OEM pistons for around 275-300 full set. Reasonable to me would be 400 or less. Maybe I'm just cheap tho. I seen a set but they were 850. Sent from my SCH-I535 using Tapatalk 2- Fanatic1074

Transmission problem
Can any transmission experts at please comment on this. I have heard that simply draining the fluid and putting synthetic will fix it. Thanks! Sent from my SCH-I535 using Tapatalk 2- Fanatic1074

Transmission problem
I did a pressure flush 10k ago and it looked like this... https://dl.dropboxusercontent.com/u/92122299/CameraZOOM-20120217131358058.jpg The guy who did the pressure flush said it was the cleanest tranny he had seen with that many miles on it.- Fanatic1074

Transmission problem
Hey guys im about to to do a motor rebuild because of low compression at the rings. The transmission on this truck has been doing some kind of rubbing/grinding sound when shifting from OD to a lower gear, like when im on the interstate and it needs a bit more power to go up a hill or pass...- Fanatic1074

5.4 Motor rebuild help.
OK well I'll prolly just try to find out if I have the pi heads and if not buy those and rebuilt them. Anyone got any tips on figuring out if u have pi heads? I have heard that they should bolt right on and provide more power w/o increasing compression a ton. Sound like a good idea? Or...- Fanatic1074

5.4 Motor rebuild help.
I have actually rebuilt a few engines before (chevy 350 and 454 and couple others) and i will have a buddy that's done some before with me helping. By cheaper i ment cheaper as in cost, not cheaper products. For instance Head gasket set on Autozone (felpro) is 199 but only 130 through...- Fanatic1074

Power issue 03 5.4
Possibly. I don't know a whole lot about transmissions. I have had a pressure flush done. It was around 125k. The tech said it was way cleaner than he expected. No chunks or shards in the pan and the magnet was clean. Tech said that if the torque converter was bad there would be carbon...- Fanatic1074

Power issue 03 5.4
Nope. Just ordered a high flow MAF. Figured maybe the stock one can't keep up with the extra flow and causing me to run lean. I'll let u now the results. Sent from my Flyer using Tapatalk HD- Fanatic1074

Power issue 03 5.4
I just lose a lot of power. It feels like the truck barely wants to pull its own weight. But it doesn't seem to be missing at all. I don't think the emissions leak is in the throttle body though I'm pretty sure the emissions leak is in the tank. The reason I say this is because about 4 years ago...- Fanatic1074

Power issue 03 5.4
Okay replace the throttle body and went ahead and added a little body spacer. Still having the same issues. However now I'm getting a check engine light. Gross emissions leak. I was curious if anyone know if this would cause the power issues or is it just another problem I have to deal with. I...- Fanatic1074
