Transmission fluid lines 1993 1500

[Pjhanlo]

Hey all,

Pulling my transmission for a rebuild due to loss of 3rd/4th.

Just went to disconnect the coolant lines from the transmission and no fluid came out when disconnected. Is this normal?

Possible Bad pump caused failure?

If it were completely full the level would be higher than the top of transmission. The trans is also a hydraulic pump powered by a gas or diesel engine. When not operating , unless something stops return fluids they all return to lowest point with gravity. That's why we check warm in park to the , " operating fluid level " .

Thank you. Fluid was probably just low, will proceed with rebuild without replacing pump

That pump will need machining/resurfacing - they all do. The pump cover and body are likely heavily scored (body moreso than cover). You'll see once you take the pump apart.

Install a Sonnax boost valve, new rotor guide, pump vanes and if high rpm, high perf, Transgo's unbreakable pump ring kit for 5500+ rpms. Sonnax pump body and rear stator bushings are also a good, low cost upgrade.
