that's the deal on a/t
none last forever like a 30k lubed, 5speed box. you can keep them going for 500k easy, if you just change the GL4, on schedule,. and clutches at 250k,
but there are NO a/t boxes that last. all fail. and that is why when found they are long ago dead, or near dead. (buy the rebuild kit hold bag in hand, all that fails fast a ton of seals, clutch pack plates ,etc.)
there are no cheap rebuilds on any A/t. (due to)
the labor to rebuild the A/t is over 10+ hours. (me be like 20hr) for a seasoned pro 10, so that be like $500 just on labor.
the parts, a $200 kit.
i have the nice video link of a full A/T build, it runs for days...so it seems... after watching it , you will know how hard it is.... tedious
and the risk,
if i build an M/T box i know it will fly.
but not a n A/t there is always risk and on the 3 speed, 2 x the risk if the 4speed. due to the 3 speed does all shifting.(VB)
the tricks to rebuild it and lower risk are a trade secret, but is easy, ill tell you, they use air pressure to test all servos.
the use air to simulate hydra. pressure, and find things, stuck , or leaking,.
the m/T if the gears are good, it's $125 bearing kit and 2 hours work (bench time)
in the end, it's a matter of luck or labor.
I've watch friends (helped ) swap junk yard transmissions 3 times, before one worked right. (the 7 day warranty deal, so must take a vacation... to do that.)
the 3sp does not need a working (x)
x; kick down. if missing it still shifts but early, and passing many not down shift. but might if next part is hooked up.
x: the vacuum modulator, on hills, if this is missing (easy hook up, for sure) it will not up/down shift going up hills. if left unconnected the a/t thinks all driving is on hills (zero vacuum) so will shift late , up hills. and reverse going down at huge 26" HG vacuum
x: TCC lockup, missing, so gear 3.5 is missing lock up. no big deal if not driving fast on freeway, 3rd gear is ratio 1:1 but the TC slips a bit. like a 1968 opel...
its a 1991 car.
if this car is a Tracker the glove box, lid has this huge sticker, called GM RPO
and all options are there.
type RPO
in my web site search box and its there.
here it is , off the offical, gm micro fiche (films)
http://www.fixkick.com/specs/RPO/RPO.html
I inverted white on black to black on white, , cool no?
the M codes are transmissions.
it's a tracker project
are all cars that?
if all 3 are the glove box, is king
even tells you if car is fed./calif or for the canada buyer.
the 4speed can be shifted manually
but you get to skip 2nd gear. doing that (per fsm method)
but if you make your own shift'er (switch) you can in fact shift all gears, manually) 1,2,3,4,R, N and lock tcc, +p/n (a complex switch but is simple electrically)
old 3L30s
https://en.wikipedia.org/wiki/Turbo-Hydramatic_180
old and hard to find used, that work, super hard. (think old hard dried , cracked seals, and super worn out clutch plates and weak pumps or leaks to/from, it.)
3L30's ended a long long time ago, the USA mail carts (jeep funny cars) use it too. and are long gone now, or USPS killed them all , driving in 1st gear for ever.
then it (Aisin) migrated to (mutated) and now 4 speed but is longer case, so all prop shafts don't fit? but maybe the 4wd adapter plate fits?
https://en.wikipedia.org/wiki/GM_4L30-E_transmission
some Chevy Trackers used transmissions (1997-2004) all the ones ive seen are 03-72LE (A44de, actual with suz, tail)
GM 41 (4L30-E) (Electronically Controlled)
transmission swaps (a/t) are further complicated buy users needs and expectations.
(what can you do with out? TCC? lock up, Power/normal switch, actual auto shifting need that? (and the OD switch)
needs vary.
with 5sp, its just one thing, no extras, or magic.
id attempt to rebuild mine, my self if mine died. (just helped my ex boss do one, 14 nights, 2hrs each) no free lunch ever on a/t labor, ...
but then adds the specter of down time,.
transwaps are endless,
they are playing with 4speed, here, swapping.
