Changing tranny fluid to synthetic

[Bob Lawrence]

Well, I decided to change to synthetic fluid.
The shop I took it to (M&M)in Tacoma put Amsoil in it, changed the
internal filter and the external filter.
Drove off down the road also after getting the engine oil changed and
noticed rig wouldn't change gears.
Tried for several blocks..no luck.
Took it back..they dropped the pan and found the pickup tube that had
an o ring replaced had a cut in it. This it turns out let the fluid
from the tranny get picked up and returned to pan without getting into
the tranny.
They replaced the o ring and the filter again (10 blocks on new fluid).
They had to replace the filter and Amsoil again at their cost.
I think with the second flush in 3 hours that most of the old ATF would
have been removed.
Anyway, problem solved.
Amazing that an o ring can cause the tranny not to pick up fluid.
The Amsoil cost $15 bucks a quart.
Cost of $450 for tranny fluid change and $300 for oil change. Not cheap.
