Tranny fluid in radiator

Asked by GuruWK897 May 15, 2018 at 11:10 PM about the 1999 Chevrolet Silverado 1500

Question type: Maintenance & Repair

Had a shop rebuild trans and replace radiator now
6 months later it over heated found transmission
fluid in anti freeze and coolant in trans fluid. The
repair shop is trying to just flush tranny. Is this
correct? Doesn't the coolant expand o rings? And
ruin seals ?

1 Answer

Thanks for your help Tom. I appreciate you taking time to answer. By the way the mechanic did flush radiator but he by passed trans cooler lines to a new external radiator mounted in front of existing radiator.
