93 tracker trans problem

[trackerjohn]

Hi again
I have a 93 tracker 1.6 w/180 trans 2wd. w/problems. here we go
When on cold take off the trans wont shift for a couple miles a hi rpm
and it hasto be started off in 1 or 2 because if it is started in 3, as soon as it shifts to neutral, it drops out of gear then i need to drop to 2 then back to three.
when warm i still need hi rpm to shift 1 to 2 it just does it sooner.
I have replaced mod
ulator and filter .Mod has vacuum to it. Any easy ideas or is it crap

[jtgh]

i have lots of questions. 3sp auto.
i will comment below in red.
does tranny slip. are you getting FLARE? false neutrals?

When on cold ans wont shift for a couple miles a hi rpm
and it has to be started off in 1 or 2 because if it is started in 3, as soon as it shifts to neutral, it drops out of gear then i need to drop to 2 then back to three. are you saying , 1, 2 then it shifts to neutral , and spins up.?
does it shift perfect in 1 selected. and there is no slipping in 1st , engine seems anchored to rear axle?
same for 2 selection on console , accel, in 1st move lever to 2 and play there
awhile, does it feel anchored in 2nd or does it slip or fail with load.?

when warm i still need hi rpm to shift 1 to 2 it just does it sooner.
you have 1 to 2 late upshifts a with both light gas, and heavy foot both ?

ulator and filter .Mod has vacuum to it. Any easy ideas or is it crap

bad governor?
and if true, no 4wd makes changing far easier.

in the book:
3L30.
most slippage is all bad news. a list of things very diff. to change.
cept low pump pressure, due to bad filter (clogged up)


if all you have is shifting at the wrong point and there is no slippage or flare.
then a governor might fix it. ( it sets basic shift points)
"The Governor is connected to the output shaft and regulates hydraulic pressure based on vehicle speed. It accomplishes this using centrifugal force to spin a pair of hinged weights against pull-back springs. As the weights pull further out against the springs, more oil pressure is allowed past the governor to act on the shift valves that are in the valve body which then signal the appropriate shifts."




comments.
gov sets shift point based on tail shaft rpm (veh, speed)
kick down delays shift with heavy foot
and vac,. mod delays upshifts with heavy load.

cheers.

there are manything that can be replaced on the tranny , with out removing.
even things I find hard to believe. that i have seen.

see next post for diagrams.

there are two govs, one for 2wd and 1 for 4wd


see dwg.

suz pn. 26190-61a50 (2wd)


this on tail shaft.
it is not too hard to get to.

cheers.

i have full pdf tranny manual if you need it.
has 2 pages, for gov. can export it to jpg and send to you.

cheers.

Yesit does have false neutral. I f i start out in 3 it willl shift 1 then 2 then drop to neutral i then drop shifter down to 2 then back up to 3 then it will shift

[jtgh]

1,2 flare (flare = total loss of torque to rear wheels, slip is something else)

fsm:
oil pressure low ( can be measured and there is a stall test and all to do on car)
band 404 , lose adjustment
valve body sealing ball , dropped out.
3rd clutch pistion seals 320,321 ,leaking.
ditto--------------centrifugl ball, dropped out.
ditto--------------pistion 322 , cracked or broken
input shaft bushing worn.

next link to chapter 7. slushomatic, FSM.

there are many AT manuals here. navigate and look, use huge blue arrow to download.

the above is chapter 7 from FSM 96
the one you want.

im no AT expert.
i just know how to do the in car tests.
and how to test the 4speed TCM puter. really cool tests can be done with it.

you might find a troubleshooter on line for TH180 AT. (base pn)
