the TCC lock on both A/T boxes, needs an ECU, marked (us-at, on its sticker , the mt ECU is marked US-MT)US = USA.
The TCC is controlled by the ECU on 3speed
the TCC on the pre 1997 cars is controlled by the TCM only
in 1997, the TCM was moved to the ECU and renamed PCM, now the PCM does both a/t boxes alone, no physical TCM box is present.l
or a manual switch (DIY) (TCC) in the cab can do the same thing, it's just a 12vdc solenoid, for TCC. (lock , unlock)
the 4speed when that connector pulled (4speed) shift solenoids (x2), you can shift 3 of the 4 gears.(unplugged, per FSM, stated test)
shift order (per fsm)
1,3,4 (skips2) this happens by virtue of the transmission shift valve inside the box (lever and cable to it) (it will never autoshift lacking the TCM,ever but you can buy a $500 programmable TCM and program it.)
With the cable unplugged,due to the now missing factory TCM
the TCM is complex ,see the schematic for it below, it runs the 2 (4speed logic) shift solenoids, and the TCM has many inputs. (all missing on 3speed and 5speed car !))
the volvo box (rare ) and others, (rare now due to age) are A40 boxes, 3 and 4 speed,
take off the bell and rear extension case and the suzuki transfire case adapter bolts on , (so they say, and is not simple project. most those posts are old, back when A40s were laying around doing nothing... )
the only kinda easy conversion is the TH180 (3L30 verson) the others are vastly more complex, if auto-shifting is desired.
The TH180 series have no TCM brain, its got a Hydraulic brain inside, so if TCC is not needed, it shifts all 3 gears, all by its self. (all the magic is inside the box)
finding good 20 year old a/t boxes is only a dream.. IMO
NO A/T is simple. 100s of parts inside , and have a low life span. (viewed in the 25 year, frame of thought)
the best way to get one, is buy a Sidekick/tracker, 89 -98 2door, with 3L30 , one that was wrecked or the engine blew up. (and cross fingers the 3speed was good)
Keep in mind many sidekicks are sitting in barns , long ago the $2500 to fix , A/T died. and was parked, ($1500 for rebuild and $1000 to put it in, )
the bad thing is the wrecking yards don't show, below , wreckers network link, is , 2door 4door or 3 or 4 speed, but usually in usa they match, 3 speed= 2 door.

one way to find used parts , is to use craigs list, use "all of craigs" to search all USA listings. google the quoted text to left here.
or create a WTB (wanted to buy) on Craigs, wanted "Suzuki sidekick/tracker 3speed automatic transmission.": see what pops up.
the transmissions, with "E" on the end, do not autoshift , by them selves ,ever.... they can't, lacking the external brain and sensors to that brain.
they have a TCM (only) auto shifted, valve body. The valve body has no BRAINS of any kind.
the VB has 2 solenoids there, see them below, (sol3 is TCC)
This box needs a TCM to shift them. (unless you make a custom switch box to do that as I have done, but turns the DE box i not a manual box doing that. the drive throws a rotary switch)

here is the GEO tracker 1996, 4speed TCM wiring
as you can see it has lots of inputs.
note page 1.
note the serial line there. (ECU to TCM) a key feature. that.
the A/T ECU talks to the TCM to let it know engine loads.
they work as a team. (the FSM covers this in the preamble of the 4speed chapter)
