WARNING: This page is about a different car, the 2001 GMC Safari, 2001 Chevrolet Astro, 2000 GMC Safari, and 2000 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
DO NOT use solutions that contain alcohol or glycol. Use of solutions that contain alcohol or glycol may damage flushing equipment, oil cooler components and/or transmission components.
CAUTION:
Flushing Fluid (J-35944-22) is environmentally safe, yet powerful enough to cut through transmission fluid to dislodge any contaminants from the cooler. The safety precautions on the label regarding potential skin and eye irritations associated with prolonged exposure are typical precautions that apply to many similar cleaning solutions. It should be noted that according to General Motors, use of other non-approved fluids for cooler flushing can have an adverse reaction to the seals inside the transmission.
