Hi all,
Hope you aren't tiring of my relentless noob questions.
My truck has a 4-speed manual with no clutch. This seems fairly common
on conversions from what I've seen, but I'm a bit confused on how to
drive it. When I shift from one gear to the next, it sounds like the
syncronizers are screaming pretty loud. This doesn't surprise me much,
and my natural inclination is to try to float the transmission, like I
was driving a big-rig or something. But this raises two problems. First,
I understand that revving the motor without a load (e.g. in nuetral)
like I would want to when downshifting is a big no-no. And second, when
upshifting there isn't any way to drop the motor rpm...you take it out
of gear and the motor keeps spinning rather than immediately falling off
like an ICE. I've successfully floated it upshifting a couple of times
by simply shifting into nuetral and waiting for the motor to spin down
to an appropriate speed on its own before shifting to the next
gear...but that takes a really long time.
So, what am I supposed to be doing? Is it OK to very gently rev the
motor to float downshift? Is there some way to slow the motor down while
it's coasting in nuetral? Should I not be trying to do this at all, and
it's just OK to shift with the motor off-speed? If someone could
enlighten me a bit about the proper driving technique for an electric
motor on a clutchless manual, I would really appreciate it.
Thanks
Hunter
