Hello all
I, like alot of you, found this site when searching for help with my first
Service engine light.
I found help here, and fixed the issues. i enjoy reading the posts and
have learned alot of usefull facts and solutions.
The problem is................ there are some seriously bad troubles
the N* can have. I find myself worrying about them.
I remember pre "light", the peacefull ignorance, the warranty coverage.
I am curious about driving habits of you guys and corosponding engine
troubles. I know a good throttle stomp is good for the engine,
but does it lead to "input shaft speed errors" code trouble?
In all the reading I have done here, I haven't seen any thought
about the meathod of running the engine to keep it "strong" that
doesn't stress the tranny.
I read the about the 2nd gear meathod, the experts who endorse it.
I am hoping we can post here what if any tranny probs, milage, and
way we blow out the carbon, maybe a pattern will show maybe not.

I'll start
95 Concours
Torque Conv at 65,000
A & B shift sol at 110,000 miles
Put around town 75% time, drive it firm around town 25%
once a month a 400 mile trip at 80-95 mph with hard kick downs to 115mph
to pass.(Car loved this and ran great around town for 3 weeks, untill I loaded it up)
I fully agree the engine loves to be used, only fear is at the expense of the
tranny.

So you just want to know our driving habits?

I usually put around 50 miles a week on my car presently because school is so close. I get 13.8 mpg and I speed over 80 mph for at least half of those 50 miles. My can has been very good to me [knock on wood]. I do a WOT about 3-4 times a week if not more. This is on my 95 Eldorado.

Hi
I want to know if driving habits can effect
trans problems.
When I bought the Shift servo A B kit, the trans
guy said I did good to get 110,000 miles before they went out.
He felt 70,000 miles was average.
I am afraid of the famous input shaft servo failing...........
I would like to hear from people whos trannies failed.
What failed? When it failed? and how they drove their cars.
I want to do everything I can to prolong the tranny life.
If the info can shed light on why failures happen, I will be able to
change my driving habits to minimize the chance of failure.
If it is just the quality of parts, and design defects ok.
I love my cad and want to drive it, not break it.
Thanks

a failure in a 4t80 trans is relatively uncommon, it is a very robust trans and can take alot of punishment and 200,000 plus miles is a fairly common number with no problems.

You are much more likely to have a headgasket failure than major transmission related issues. You already replaced the solenoids, so the transmission should be good to go for a while.

:yeah: times 10000. I am truly in love with the 4T80-E in my Eldo and our SLS. It is snappy, quick thinking, and very reliable [knock on wood]. I hope my trans makes it to 200K. I am at 127K right now.
