I've decided to purchase a torque converter for my car after spending a grand in Long tubes and realizing it only shaved off 2 tenths. I've got LPP LTs, a cat-back, lid, pp tb, and 2.73s. Stock trans, Stock motor. My guess is that the car simply needs a good kick in the pants to get going down the track and from what I read, the stall is the way to go.

I have a Hayden tranny cooler thats a few years old but I'm sure its still good. And I ordered a tci flexplate along with the Yank Super Stock 245mm 3600 stall 2.5 STR.

I'm just wondering if theres a few things people have learned along the way about what ways to keep the setup running strong. I plan to daily the car and I just want to know how I can protect my investment better. Any preventive maintence or do's and do-not's? I'm a noob with this kinda thing i know! Thanks.

Honestly, I'd swap your 2.73 gears to something like 3.73s. It'll help make any converter you choose seem much tighter.

X2 on what Squit said and make sure the cooler is a good one. Also a good tune would make a big difference if you haven't already gotten one.

It should run strong with all the new mods, but she will be a tire fryer

I really liked the way my 2.73s felt with my yank3600, but then I got a swapped a set from my friends M6. My guess is that it will knock off about 5 tenths off your time if you can hook.

i would agree put some gear and a good tire on her and you will snap you neck and drop several tenths plus+ well worth it

Ok cool. Is it true that running this setup(3600 and 2.73s) can fry the transmission? People are all over the place when it comes to this topic. I figure with the tranny cooler it should be ok though.

The 2.73s gears do provide a harder load to move, so yes its harder on the trans. I would at minimum run 3.23s.

I don't have as big as stall as the one you want to get, [fuddle 3000] but I did get it installed about 40,000 plus miles ago. And up untill last february I ran it with 2.73 gears.
Four years ago I added nitrous to all of the other bolt on's, [ lid, lt's, cat-back, underdrive pulley]. I may only be hitting it with a 75 shot, but I have used 20 plus bottles.
Last summer I put in a gm Hotcam.
The tranny?
Still going strong
Now I cannot gurantee that your tranny won't fail on you.
What I can tell you is many, many people here run a 3600 to a 4000 stall on 2.73 gears
and have done so for some time w/o any issues whatsoever.
Just make sure you change the tranny fluid on a regular basis, check that filter and DO NOT delete torque management.
Assuming your a4 has been taken care of you should be just fine.

Why is deleting torque management a no-no? From what I had read, I thought it was recommended when going with a bigger stall...

I would have to say that keeping the TM in his car is a personal preference as is removing it which most motor heads will do. If keeping your original stock tranny alive is your only goal, then leave it in, but with all of the modifications that are already done, keeping TM in isn't going to save anything.

Manually downshifting and kicking the tranny down in passing gear at wot is the biggest killers of the 4L60Es along with 6600+ rpm shift points.

Your car will rarely duplicate the same numbers at the track with TM still controlling the timing. If it's just a weekend cruiser and you could care less about performance results, then leave it in, but then why put a stall and all the other bolts, cam etc?

We beat on ours like they owe us money, but you can do that when you have a good tranny builder.

Well, I'll probably keep TM disabled since I would like to get extra power. I suppose the question here is what would be the loss if its left on. Does leaving TM on really slow it down that much for extra reliability?

As of now this car to me, is my daily driven and raced 2-4 times a year. I'd like it to last but Its gotta be fun too, otherwise why get the car.

TM can really save a stock tranny.You don't need as harsh as the stock table's but pulling timing on the shift helps the clutch packs.

I'll consider leaving some TM on. I guess I gotta see how it drives when I finally get it installed.

Agree with those that recommend gears. My car was originally 2.73 but I switched to 3.42 before I got a converter. Knowing how the stall feels with the gears, I'd hate the looseness of driving around with it and 2.73's.

As for TM, I've reduced it, but leave some in. I find that the 1-2 shift hits too hard and will break loose a little at the track with it completely eliminated. But I do have a Transgo with one washer in the 1-2 accumulator ...

update: SS3600 installed along with 3.42s. I'm going to take it easy on it for a little while, let the parts break in, but then I can't wait to see what it'll do at the track. Thanks for the advice.

get some red alto bands installed when you have the trans out...that is all I have on my stocker...it has seen both the ss4000 and ss3600 with over 200+ track passes and 100 or so of those passes shifting at 6900...

the key to keeping to stock trans is keeping the heat out...get a large trans cooler and no hot lapping...

my dad and me are running low 10s on red alto bands and stock 4l60e's...

great converter choice you are really going to like it...

dannyz

Is that so?
Using that analogy would you also say its pointless to install a nitrous kit and only run a 100 shot?
Show me anywhere where someone has modded their car and then ran slower due to tq mgmt being left in.

dannyz

Yes, Bro inc. Everything you say makes perfect sense.

Again, usiing your own ideas on the only way a car should be built, you need to start with at least a 28' tire. Then you have to do the correct susp. mods to make them stick. Then you gotta do a 12 bolt. After that comes the trans.
So what do we have thius far?
A 13 second car.
Thankfully, most 4th gen guy's don't follow your line of thinking.
Plenty of guy's out there deep into the elevens and even high tens on stock tranny's.
Granted, deleting tq mgmt will squeeze a bit more performance out of the trans. But has anyone done a test to see just how much of an improvement you will see?

ive read all this just now and if the tranny isnt built i would leave some tm in it

dannyz

Sound logic.
