A/T - 125, 200C/200 4R, 700 R4 Hidden Residue Build Up

TSB 86-23 (May)

SUBJECT: 125 - 200 C - 200 4R - 700 R4

HIDDEN RESIDUE BUILDUP

PROBLEM:
After rebuilding a burnt 125, 200 C, 200 4R, 700 R4, and with new fluid circulating for 10 to 100 miles of transmission use -- valve stickage occurs.

CAUSE:




Inner cavities (as pointed out) build up a residue which, if not flushed out, will gradually loosen up and float into the valve body, causing valves to stick.

CURE:
Flush, until only clean solvent emerges from the piston supply holes.
