Truck is Down! TC and Trans are junk.

[tdeal823]

OK guys I am in need of some help. My old trusty is down. I sold this truck to my dad last year when I bought another truck. The truck with the bad trans is a 2002 F250 7.3 auto 4x4. Has cold air, 5" exhaust, TS chip, and gauges. 198,000 miles.

I am going to have the trans rebuilt. A good local transmission shop suggested the rebuild with aftermarket better parts, new HD converter and mild shift kit.

Question? Will I need to do anything with the TS chip. It is one of the flee bay specials 20-40-60-80-110 I think. Does this chip do anything to the line pressure of the trans? Wondering if I need a new chip.

Thanks guys
Tony

ditch the shift kit and get a valve body instead.
john wood, bts valve body etc. are good.

i cant remember if they change line pressures in ts canned tunes. id search around you might be able to find an answer on here

just a mild build no a crazy one tunes should be ok, just not up to the full potential it could be. might shift harder then it used to...

Valve body vs shift kit? I thought that shift kits changed parts on the factory valve body. So what would be the advantage of a whole new valve body?

I have been trying to search for answers on the TS chip.

Trans is done and back in the truck. Seams to shift just right. Now I have a burst fuel line down in the valley of the intake.

I wonder if I could use steel branded line and not the factory bent steel line.

I would ditch the canned tunes and talk to one of the big names about burning one for your truck. You have gauges though, so you can tell if the canned tunes are causing issues or not. I was having shifting issues until I put in a JW valve body on advice from here. It fixed me up nice and ended my worry about scattering my transmission on the side of the road. I couldn't tell you the difference between a new VB or a shift kit, I just know that the VB's are built for tuned trucks. JW was great about asking me what I've done to the truck and what I'm looking for with the shifts. The VB I received performs exactly as I want.

I don't see why you couldn't go with a steel braid line, as our fuel pressure is gained from the HPOP, not from the fuel pump. Ensure the line can handle at least 100psi. We're only looking at 60psi or so, but running a hose at max rating all the time will wear it out fairly quickly. Keep in mind carb's look for 2-5psi, gasser fuel pumps are typically 20psi max. So don't just grab some stuff off the shelf at the parts house.
