Sam I was surprised to read you couldn't find anything about the Automatic
Trans that is different from the turbo to the non-turbo. There are more
differences in the two transmissions than the engines! The turbo auto tranny
is the one used in the SVX and is really a completely different trans than
the non-turbo version. Unlike the non-turbo version, it also has a stand
alone Transmission Control Unit (TCU) that operates completely independently
from the Engine Control Unit (ECU). When mine started to go out I did a
nationwide internet search for a solution cause my car only cost me 10 grand.
A trans from the dealer was priced at 5 !!! It is the most complex system
in the car and not just anyone should be entrusted to work on it.
Most DEALERS don't even have techs that are turbo auto trans qualified, they
just remove and replace when there's a problem. After contacting about a
dozen sources that sounded like they knew what they were talking about, I
felt good to find someone that could rebuild mine for a grand. One thing
though, I've driven and enjoyed manual trannys most of my life, but this A/T
can really kick butt when you stomp down. It has a kind of fuzzy logic that
interprets throttle speed and position so that the shifts are harder and come
at a different place in the RPM band when you really punch it. My auto trans
and heavier wagon will kick you manual trans guys cars in the tailpipe. Come
on, somebody flame me, just come on!!!

Well for starters, if both were stock the statement would be
true. However, I don't feel that I'd have any trouble showing you what '91
turbo sedan taillights look like. Secondly, any good A/T shop should be
able to do a Turbo AT rebild; a local hick did my parents', and it's got
100,000km on it since then with no issues (the trick is to be careful and
pay attention, he says). $2500CAD was the rebuild cost.

William D. Robinson
Sam ?s Turbo AT vs non-Turbo AT
Larry Witherspoon is correct about the turbo automatic being the same as in an
SVX. That tranny and TCU also controls torque split. The raw guts of just the
tranny portion (not case, center diff etc.) are the same as in a Mazda 626 of
comparable years. Th extra strain of the weight, power and AWD of an SVX causes
that tranny to be a known weak link. I learned this on an SVX site. Our SVX
performance nutball counterparts say that one should add a stand-alone
transmission cooler to an SVX at the first opportunity.
