I just changed the tranny on my '98 Expy and need to knowwhat I can use to clean and flush out the integrated transmission radiator cooler and lines. Thelines have not beenconnected to the tranny yet so I'll feed pressurized airalong with the solvent to runthrough the inlet lineand drain the gunk through the outlet lineinto a pan for disposal. Any ideas as to what solvent I should use? Thanks.
