1991 3spd auto ""HELP!!!"
#16
yes TPS is that. (aka throttle angle sensor)

http://www.fixkick.com/JARGON.html
4sp 02-72LE is totally electronic shifted unlike the 3L30, then only similarity is they both have planetary gear sets.
the 4sp shift via electric SOLENOID valves.
The 4sp shift by virtue of the TCM (brain) The Trans, control module.
the TCM and ECU work cooperatively (any A/T labeled ECU works

my tcm page covers the TCM inputs and outputs,
the TPS is only one minor input to the TCM. (TV cable , engine load (via serial data line), engine RPM , vss (veh speed) brake signal, TPS, range selected,4L, OD slected, and Power/Normal switch)

these cars are rare, done here we see one every 3 months.. very rare.
and used parts even harder,
the there are 2 dealers on my buy parts page, that still seel parts. (no cars, but sell parts)

ok i see your frustration,
you dont like 5sp , no like shifting by hand.?
so need and auto shifted car.
many cars are sent to the wrecker for just that.. huge, the new trans, is like $1500 &up and same for labor, who's going to put $3000 in dead car?
this economic fact puts them in the junk yard or parked in a barn for ever.

the 4 speed shifts manually, with no TCM (per my page and FSM linked pages)
doing so, works like this:
1,3,OD (skips 2nd) most folks would not like skipping 2nd every day. (but some do it)
http://www.fixkick.com/tranny/slush/slid...l-mode.jpg
But on my 4speed page
you see this. (make a switch and shift all gears)
http://www.fixkick.com/tranny/TCM/test2.jpg
shift to drive, then flip the switches. (one could make custom electric shift'er and shift the box through 4 gears, forever.

now how does the TCM work.? (it just a small computer, )
here are all my photos and docs on TCM
here is the 96 schematic, (the serial line is load data sent from ECU to TCM and engine RPM "nothing trivial" that.)

http://www.fixkick.com/tranny/TCM/FSM-TCM-SCH.pdf

4sp, facts.
http://www.fixkick.com/tranny/slush/OD-f...0what.html

4sp in to a 3sp body, is covered here. on SWAPS
see example 1 on swaps page
http://www.fixkick.com/SWAPS.html#Tranny_swap

why not just drop in a good engine on the dead 4speed car.?
but needs 8v for 8v or 16v for 16v.

the hard part of automatics.
it takes a good running engine to test it. ( so when you see a dead car, you get to fix the engine first to see if the trans is even 1/2 alive, most aren't)
on 5sp, one gear always works, (clutch good)
usually they all do , but some may make noise. 5sp.

on automatics, 1 part in 200 can kill it, they are complex and cant handle say a dead bug landing in the wrong spot. (frail)
(weak pump, bad clutch packs. , leaking seals (huge) inside or accumulators leaking, and a huge lest of doom things, inside, all frail)
the 4sp is better than any 3sp, less box parts to mess up, and the shift solenoids can be tested easy and replaced easy.

on the other hand a good 5speed will last the life of the engine if you do 30k mile GL4 gear lube services. (never seen any A/t do that ever)
(ive even gone 250k miles on a clutch easy)

the real problem is the pig in the poke sack deal;?
does this car x have a good transmission, engine it , dead.
personally
I look at all 3, and go, which car do I like the most. (usually very easy , decision)
and make it all run like new.
no matter what. 1 step at a time. (id get the engine going good first.) then start testing the transmission.
id even overhaul the trans if need be.
the a/t can take 3 days work to do that, with the full kit in hand. (or a week, now that im so old)

parts
the both the 3sp and 4sp are not unique, both are based on old designs. (with 4wd rear end caps, added. (adaptors)
the TH180, was used from 1970 until beyond, 2000 year. 3l30 is only 4wd version with tcc.
the A40 series Aisin ™ box. a44de is what the 03-72le is + same 4wd adaptor. added.... so the box is used on VAST cars world wide, Toyota, even old volvo.
and all major, transmission parts dealers sell the parts and kits and full service manuals. (on CD)
any transmission shop in town can overhaul it, for sure. any Sidekick a/t box.


really if you dont break a suzuki sold only part, it's not hard to fix any sidekick
if you do the parts are here. (ask for p/n and ill give you it)
like this NJ , link. (they do have parts and can take 2 weeks to get, from way DEEP warehousing...)
http://www.suzukiautomotiveparts.com/inf...gin?dpt=11

now the engine
we can get most the parts for the engine,
finding used blocks is not easy . (short./long or stripped naked)
but all the other parts inside engine are still sold. (or rebuilt)
Only the MAF sensors are very expensive. but Cardone sells rebuilds and ECU/s

name a part, and we can find it.
or use
car-parts.com
used.

a40 boxes

http://www.shinseiauto.com/japanese/transtar/Toyota.pdf

this is what the A40 fits. vast cars.
just some.
notice how all parts in side, have a spare. listed.
many sellers... of parts, inside.
my wifes mazda had one. even used on some mini vans.

a44de (the e means electric shifted, all 4 gears)

the tcm shifts by internal TCM memory tables tables using all sensors as inputs to said table.
the table results are here.
the transmission has throttle cable TV cable inputs and TPS and engine load, road speed to govern shift points (4sp)
the charter here shows the results of those internal tables (crude chart)

the console P/N switch (power/normal) cause the 2 charts.
