Thanks for posting that Tom... I PM'd him yesterday when he started this thread saying the same thing... It does not work all the time... but sure is a good bet for many symptoms which can be caused by clogged orifices in the shifting body... and it is cheap compared to most other methods.... the last few times I have posted suggesting it I got some resistance.... I have had some dramatic and instant cures with it as far back as 1975....at worst it will help clean out the system and that varnish will be evacuated with the fluid change.
