95 sc2 saturn Trans shifting hard

95 sc2 has been shifting hard in 2nd, now spreading to other gears, only
has 52,000 miles on it, replaced fluid religiously! Help

 

Automatic or stick?

 

Sounds like an automatic since they are changing fluid religiously, but you
are correct in that the OP should have been more clear if they want a
meaningful reply. If it is an automatic, then try the reverse slam fix at
the Saturn Forum:

This is cheap and pretty easy to do. Also make sure all the grounds and
battery are good since the computer controls all shift points. The last
thing to check are the shift solenoids. I posted a procedure here about 6
or more months back. Check the Google archive. Good luck.

It is an automatic!

 

Bob, I have read numerous replies that you have posted and have read and
actually done the reverse slam as of last night,,,so far so good,, but i
do have questions about it,,,does that work with any transmission or just
saturns...i have 89 buick century kinda shifts hard also...would that help
that....possibly...oh and with the reverse slam,,so you empty out the fluid
that you did the reverse slam with to get rid of the crud???

 

I have no idea if it works with other vehicles or not. I'd suggest you
contact the original poster (Wolfman). As I understand it, using fresh
fluid, filter and a trans additive and then getting the trans fluid
extremely hot by using the reverse gear causes the debris and gunk in the
trans valve body to become dislodged and then trapped in the filter and/or
drained out the drain plug opening. I believe the Saturn used an
electronically actuated, computer controlled solenoid valve body. I believe
the TAAT was unique to the Saturn. I have no other GM vehicles so can't
comment on if the same principle or similar design was used in other models
or if this would be helpful.

I'd suggest looking on Google for GM forums to ask there or do more
research.

Google this group for "Valve body"

 

Every transmission GM has built for the last decade or so has used
solenoids. One thing that stands out on the TAAT from the rest of GM's
transmissions and everyone elses that I know of is that the TAAT has the
easiest valve body to access. However since the excess fluid from the VB
doesnt drain straight off into a pan it might be a reason it gets
crudded up. I cant say for sure though. I think heart surgery is often
less complex.

 

Thanks Bob,, appreciate your comments and appreciate you giving your time
to help other folks with problems...
