Lol, I have OSB & Cardboard on the table. Kitchen table is probably the best place for me to do the transmission work. Transmissions are really finicky about dust, dirt & debris. That’s actually one of the reasons I’m doing this at home. I can control the environment, I cant control the environment at the space. Someone could go directly next to me at another table & do any activity that could cause foreign debris. The way I sold it to my wife is, Do you want me re-doing this in a short period because the environment?
The transmission shops I have seen in the past have a separate room where the transmissions are rebuilt.
