Lucas make a manual tranny fluid??
Ive personally seen the auto fluid work wonders.. My friend put it in his burnt up tranny (read, no go no mo') and it shifted like it was new. I wouldnt have believed it if I didnt see it.
I used their oil stuff a few years ago. I had a Camaro that had a rod knock for about 3 years and it held up. It got so bad, I was running 5 qts of Lucas and 1 qt of 90w140 to barely get oil pressure
