I'm trying to figure out how to effectively calibrate the tranny
dipstick. I've seen a few different approaches, the easiest seeming
to be pulling the vacuum modulator and filling the tranny until fluid runs
out the hole, replace the modulator, then marking the dipstick "full" line
at that level. I assume we also need the tranny pan level in order to do this right.
My questions though: does the tranny have to be hot
(ie, just driven) and does the engine have to be running
while checking this? Can I pull the modulator before starting
the engine, start the engine to fill the torque converter, add fluid
until it flows out the modulator hole, then mark the "add" (cold)
line on the dipstick instead?
I'm really not looking forward to lying in close proximity to
the underside of a hot, running, engine in order to reach the modulator...
Details on how to do this safely and correctly would be greatly appreciated.
thanks
