Default Transmission Life and High Stalls

I have my purdy little Collectors Edition now, and I am half-tempted to keep her relatively stock so maybe it has a chance at holding some value. But of course I know a stall would wake up this beast hugely.

So if 10 is a stock transmission life, what effect does a stall have on a scale of 1-10?

I would say very little effect so long as you keep the temps cool (under 200) and change the fluid often.....

So it doesn't wear on clutch packs anymore than a normal TC or anything like that?

I don't even wait that long. New fluid every ~3K and new filter every ~6K.

...and I am half-tempted to keep her relatively stock...
Stock is boring. Get the stall.

Like they said....
One thing that I always tell people that ask about mods-I don't think the stall itself would be extra damaging(so long as you keep it cooled) so much as the temptation to "drive it hard" with the new found performance. It's like longtubes/exhaust. Technically, they WILL increase your MPG, but everyone sees a decrease in MPG after install. Why? Because it's so much more tempting to have a lead foot after you have more power. Think about it.

I suppose that makes sense, when I got my new car I was noticing I was speeding a lot because I was driving it like I did with the TC. Took a little more foot on the pedal to get her up to speed.

I would get a stronger flexplate if you are going to get on it. I cracked my stock one Friday night and took out my starter with it. Maybe torque management isn't such a bad idea.

I bought the GM pan with a drain plug which will make fluid changes much easier. I plan to change mine with every other oil change.

a cooler and regular fluid changes definitely help with life. Consider them mandatory with a high stall.

A stall adds wear. Even with TM, you are putting more torque through the tranny. A 3200 stall creates less wear than a 4400 and won't hurt life too much. For daily street driving there is little or no effect; it only matters how often you are running at WOT.

It's hard not to open her up a bit, I figure it's better for gas mileage to hit it hard to 40 or whatever and let it lock up. Than spend a quarter mile at 3500 RPM sucking down gas and attracting cops.

I may be wrong however.

So I see the "it's the temptation" argument proving true.

@ 3500 UR NOT (sorry bout caps) not spending much more fuel than baming it to 40mph then lock up. I actually had my lock up lowered to 35mph cause I drove like a grandma during the week...and lock up only occurs at part throttle so @ WOT it didn't matter...that would be an Idea...also...Torque Management...you can set it at like say 50% below 30-40% throttle possition so it's not so rough, but get's the next gear w/out much clutch wear...then above whatever threshhold you set it at have the TM deleted for those um...."Redlight" encounters.....hehe.... 110,000 on BONE STOCK tranny...I gotta be doing something right...and that's with TNT 150/100 shot or My MTI Stage 2 heads and X1 cam....

I set my TQ reduction tables to 50%. That's a good idea. I really didn't notice much difference in feel between backing out the TM all the way and just doing the 50%. But then again, I have an '00 car and they don't suffer from very many TM issues. '02 cars have A LOT more timing issues with TM and usually benifit quite a bit from removing it.

I don't see a ~3500 stall causing any extra tranny wear so long as you keep the fluid clean and cool. Driving it hard won't kill it either, so long as the temps are under 200 and the fluid is changed often. Fluid changes are so important yet so many people seem to skip past it for too long. Once you get a deep pan w/ drain plug it's so easy to change it I just do it every 3K because it goes so quick and the fluid is cheap......

PS. I wonder if the reason the '01 and up cars have the extra TM is because of the weaker flexplate for '01 and up? I beleive the '98-'00 had stronger flexplates, correct?

Josey, did your car come stock with 2.73s? I'm just wondering because my car locked up at 35mph stock with 3.23s......

No...I had it raised when I did my LS1 edit then realized I was driving 80% of the time w/it unlocked...so I changed it back down. Mine came with 323's....it's been a year or so since I changed that stuff so don't quote me on "stock" lock up.
