Q: Why can't I reuse the transmission fluid I use for flushing?
A:
The very fine metal and clutch material debris from the transmission failure in the ATF cause failures with the hall effect speed sensors that are used to measure the flow rate. To avoid costly repairs, expensive filters, regular maintenance, and problems caused by a partially restricted filter, the filter was not included.

Q: Why doesn't GM publish a specification for auxiliary transmission oil coolers?
A:
The auxiliary oil cooler used with GM vehicles does not contain an internal Turbulator plate like the radiator tank oil cooler does. Therefore, there is no internal restriction that would affect the flow rate through the oil cooling system so a specification for an auxiliary oil cooler is not required. Keep in mind, kinks, and damage to the auxiliary cooler and lines can affect the flow rate through the system.

Q: What is the difference between steel and aluminum oil coolers?
A:
The aluminum oil cooler tube is slightly thinner in construction than the steel oil cooler tube, which affects the oil flow rate. The fitting that is protruding out of the radiator tank easily identifies the aluminum oil cooler. Refer to the Quick Reference card provided with the J 45096 to identify the proper flow rate for the aluminum oil cooler.
