Re: grrrr- no trans filter
"Spinner" does it the redneck way-LIKE I DO.
1. Two five gallon buckets.
2. One empty, one full, of my desired trans. fluid.
3. Disconnect the trans cooler lines and put the output into the empty bucket and the intake into the full bucket-of trans fluid, of your choice.
4. Run the engine, bring it up to operating temp. and shift through the gears.
5. After about five minutes, you have a trans. "flush".
A lot of wasted fluid but-done. A complete flush. No machines.
I see a lot of trans. failures due to WRONG fluid. Buy what your owners manual says.
I trust the "machines". It's a lot simpler and better, IMHO.
