Phoenix and a Ford HD 4R100 transmission
 

My truck ('01 F-250 7.3 PSD 4x4) has a HD 4R100 auto transmission in it that replaced the original standard 4R100. it also has a Ford AIS intake and MBRP 4" exhaust.... Otherwise stock.

Would I get a chip with Sandard Tunes or is the HD 4R100 considered a modified transmission requiring Custom Tunes?

Pretty sure you can just get the regular tunes if you don't have a modified valve body in the trans.

Ok, good, I didn't want to have to get custom tunes just because of the transmission since the rest of my truck is pretty tame (intake, exhaust and guards). The HD4R100 improvements are this:

• Enhanced Torque Converter for better performance and longer life
• Oversize one piece case bushing for improved durability
• Enhanced Forward, Direct, and Intermediate Friction plates for longer life under heavy load shifts
• All new special upgraded steel plates
• Center Support Enhancements for improved gear train life
• Mercon V-OIL for greater heat resistance
• Oversize Pump Gear Set for improved oil flow
• Upgraded Extension Housing Bushing for improved durability
• 45 Element Intermediate Sprag for greater strength to withstand heavy loads
• Special coast clutch drum for improved engine braking and increased durability
• All new iron planetary assemblies for improved durability
• All new one way clutches for improved durability
• All new electronics for improved reliability
• Revised calibration gives better shifts for heavy duty use
• Improved gasketing for reduced leaks

How is the 4R100 HD holding up?

Doing vine.. Just did a 1100 mile trip pulling the TT and a family of 4 from Atlanta to Destin to Myrtle Beach (TS Debby chased us out of Florida) and back to Atlanta last week.

the transmission stayed good temperature wise, but I think I'll still upgrade to the larger 6.0 cooler.

We have about 13000-14000 miles on it now.

Doing Fine.. can't you edit posts on this forum?

You should be able to....heck, I just edited your post. :lol:

lmao...that's funny right there :thumbs up yellow:

Did you get the standard tunes? I am in the same boat with a new trans but they did add a shift kit to it. The trans guy said he can replace it if need be and thinking for the extra $200 for the custom chip I can have the trans back to stock for no cost...
I did have the billet torque converter with low stall added.
Once i get all info together I will place my order.

thanks
