Transmission Shifts Hard - Valve Body?

My 93 SL1 with SOC engine began shifting hard recently. I've been told that
it is probably the "valve body", which is exterior to the transmission. Has
anyone out there had experience in changing one of these? Is it easy to get
to and is it a hugh job? Its a $1200 job at local Lee Myles transmission
shop. I can get the valve body and actuators for about $550. Any helpful
comments will be appreciated.

It's not a HARD job but not necessarily one to be taken on by someone who is
inexperienced either. FWIW I bought the VB for my own at the dealer and it
was only $195 after core charge. It took me about 2.5 hours to do on my SL2
but that was because of 2 things 1. I spent alot of time exploring things
and the VB itself. 2. It was the first time I've ever looked under the hood
of a Saturn. I do have alot of wrenching experience though and am well
equipped for tools because of it. FWIW if I had to do it again I could get
it done in 30 to 45 min.

One should have a book, a good torque wrench, and the proper tighting
sequence. You're lucky its easy to get to. I think those prices they
gave you must be a generic quote. It doesnt sound like there's that much
labor involved.

I had a quote from a local trans shop two years ago they wanted about $400
for the job.

Thanks to all for the good information. One more question. About half the
price of $550 I was quoted for the parts was for the actuators. How can I
tell if the actuators need to be changed along with the valve body? Does
anyone other than the dealer sell these parts?

You can check the shift solenoids with an Ohm Meter. You will need to
know their values at a given temperature which should be given in a good
manual. From my TranX 2000 documentation the resistance of each should
be the following.

There is 7 actuators and it list them with all the same values.

TAAT Transmission

91-92 2.5 Ohms Cold / 4.4 Ohms Hot

93-up 4.0 Ohms Cold / 6.0 Ohms Hot

Hi Larry:

I have a couple of questions about replacing the valve body on a 93’ SL1
SOHC. I haven’t been able to find a manual that covers this subject – do
you have a recommendation? Haynes doesn’t cover transmissions, nor does
Chilton. Chilton has a tranny manual, but doesn’t cover Saturn. My local
library has ALLDATA, which has a some transmission information, but doesn’t
cover removing the VB. If I can’t find a manual, is the removal simple
enough to be done without? I’m hoping that the removal process will be
obvious and that if I reverse the process I will be able to get the
replacement on. I assume the VB is under the plate on top of the
transmission – is that correct? Any other advise?

Thanks much,

Gary

Theres more to it than how easy something is removed. Your valvebody is
the heart of that transmission. Improper torque to it and one vain may
shoot fluid past the gasket and into another and cause major damage to
your entire transmission. You'll need to hunt for a real Saturn service
manual. You dont need to find a 93 only manual. I think they're the same
upto 95-99? 91-92 is slightly different.
Someone ought to make a on car repair webpage for TAAT valve bodies.
Theres enough people out their seeking this info.

Thanks Larry:

I found a Saturn 91-94 factory transmission manual on E-Bay for $9.50,
including shipping.
