• Erratic shift timing
• Oil leaks

Leaking valve end plugs in pre mid-83 units, or worn 3-4 shift valve and sleeve in mid-83 and later units.

Plugs are manufactured of high-quality aluminum to resist wear. The O-ring on the outside diameter prevents leakage between the plug and the valve body. The medium 3-4 plug is replaced by the 3-4 shift valve assembly after mid-'83.
