A/T 4speed fails, car wont move until hot.
#97
i got confused, there is cold idle speeds , hot idle and stall speeds/
what is the hot idle speed, in RPM, hot in park.? with foot off gas pedal. (900 , 1500 2000 rpm with foot off gas?)
or 500 , 700, what?
"My idle has never been 800.
Not even close to 800. "
these to inputs to me , tell my zero.... see why?




1>2 shift 13mph. the chart again shows, this can happen, take off in drive, get speed near 15mph and lift foot of gas pedal, is goes to 2nd, just like the chart shows. we can calculate the rpm but that is just 1st gear x rear axle ratio. easy to do . but not needed..
what matters is right foot, speed, rpm and if car is on flat ground or not.
tell me what you expect first then what happened, that made you think something was wrong.

the TCM question
yes there are some folks driving with no TCM at all
skipping 2nd.
how you like this , you'd have to try it.
but you can see going up tall hills and skipping 2nd would be hard on the 3 gear clutch pack as it slams down.
but on flat ground piece of cake. a cake walk.

as you can see unplugging the TCM solves many issues.
here ill list them.
my trans does not slip. an any of 3 gears. (2nd cant be tested)
the other non 2nd gears, all work. great, and with full load up hills.
the TCM is not there, so if symptom is no gone then you found a big clue there. no?
you can see engine power for what it really is in 3 gears, good bad or ugly, no TCM to fool you or bad inputs to same.....
that is its purpose. in the FSM.
how you can use it , is up to you.

what is hot rpm
foot of gas.
in park
?
you never once said. or i missed it
keep in mind i cant drive your car, if i could id see like 100 things, in 5min driving. vast things, sounds , speeds, vibrations, power, misfire, bogging, surge, (?) , and lamps and gauges. and what the road is doing.
none of that , can i do..... me blind
