Symptom: Transmission Leaks Fluid
Leaks may lead to additional damage if left to continue. It is normal for
a leak to develop under various conditions. Metal contractions due to
temprature changes can create a leak. Brittle gaskets may properly seal
once it is warmed by operation and coated with fluid. Remember to check
the fluid level and quality before long trips. Normal transmission fluid
is pink and does not have a sulferous, or burnt, smell. Call to schedule

Symptom: Inconsistent Transmission Operation
You may notice that your vehicle works, but is inconsistent. For example,
it may only work when warm, or only for a few miles before stopping. Heat
changes can cause metal and rubber parts to permit fluid to leak or block
fluid flow at the wrong time.
Possible Cause:
Heat changes can cause metal and rubber seals to permit fluids to leak
or block flow at the wrong time. In addition, a transmission filter can
clog after a minimal driving and cause the transmission to stop working.
