What size holes do I drill in the E4OD accumulator valve body?

Drill two .076 to .093 inch holes through the casting at the marked "X's." The sheet says it's not fussy, and if the casting already has a slot there, no drilling is needed.

What spring colors go in the 4th and 3rd accumulator pistons?

Install three ORANGE springs in the 4th accumulator piston, and a SILVER-ORANGE-WHITE-ORANGE sequence in the 3rd accumulator piston.

What do I do if the casting has no hole EX for the solenoid pack?

If there is no hole EX, drill six 1/8" holes as shown in the illustration, then drill one more hole through the partition under "X." If hole EX exists, install the solenoid pack as it is.

Is the steel line regulator valve available separately?

Yes — the steel valve furnished fits all locations and is now available separately as E4-VL-LR3 in a pack of 3.

What springs are used for the 2nd accumulator?

Per step 3, install the steel line reg valve and 2nd accum springs as shown: a reused spring, plus three ORANGE springs and a SILVER spring.

This is Page 3 of a shift-kit / valve body reprogramming instruction sheet for the Ford E4OD automatic transmission (document code E4OD-HD2, dated 13 Feb 04). It covers five installation steps. Step 1: Accumulator Valve Body — remove the line mod valve and accumulator valve, then drill two .076–.093" holes through the casting at the marked "X's" (no drilling needed if the casting already has a slot). Step 2: install new springs into the 4th and 3rd accumulator pistons — three ORANGE springs for the 4th, and SILVER-ORANGE-WHITE-ORANGE for the 3rd. Step 3: install the furnished steel line regulator valve (also sold separately as E4-VL-LR3, pack of 3) and 2nd accumulator springs (three ORANGE plus SILVER, with a reused spring). Step 4: install the short BLUE spring with the line mod and accumulator valve assembly. Step 5: Solenoid Pack — if the casting has hole "EX," install the solenoid pack as-is; if not, drill six 1/8" holes as shown plus one more hole through the partition under "X." Illustrations show the valve body castings, exploded valve/spring stacks, and numbered drill locations 1–6. A reader learns exact spring color sequences, drill sizes, and casting checks for this E4OD modification.
