Sorry, the glycol test does not prescribe the transmission replacement.
The following must be done depending on the result per manufacturer specs:
''- As of a glycol content greater than 100 mg/l. Exchange radiator, flush torque converter, lines and transmission.
If the complaint is still reproducible after the flushing routine, only the torque converter should additionally be replaced. ''
Result of the test is shown as a color of the test paper. Test itself is quite specific.
If the transmission does not exhibit any symptoms after the flush, transmission is considered to be in order by manufacturer's specifications.
Of course, if transmission gears are slipping after the flush, then the coolant has damaged clutch plates, torque converter replacement will not help.
