hi I have a 98 Camaro ss ls1 only 55,000 miles on it I don't plan on tearing into the engine till atleast 120,000 that being said I am wanting to know if my stock trans with a stall maybe ss3600 or ss4000 hold me till then ? my car has fast 92 intake fast 92 tb, full exhaust, tune, tranny cooler, sfc, rear control arm relocation brackets..... I want to leave the engine internals stock an beat on this car for quite a few more years till I need to pull the engine.. so can I get a way with throwing a stall in my stock 4l60e or is my money better spend getting a built trans with a stall and do you have any recommendations?? as always everyones advise is greatly appreciated

I have read a lot of guys installing a stall w higher mileage w no problems. My 99 SS has 114K on it and I am adding a stall (SS3600) in the next couple of weeks. The "tune" has a lot to do with the longevity of the trans ( once stall is added). That with the cooler should prolong the life of the otherwise stock 4L60E... Just my opinion...

We just had a 40+ post on this subject which should give you lots of insight and perhaps help you make your own decision:

I did see that they were all great posts but I was hoping to get advice given my specific setup

mrvedit

You will have a perhaps 12.5 second car, the same as many/most in that other thread; the specifics really don't matter, just the resulting power/ET.
I would stay away from full slicks with a stock trans though; drag radials should be fine.

Ok great input thanks should anything else be replaced while I have the transmission off

mrvedit

At 55,000 miles you should be OK as is.
However, I typically recommend installing the Sonnax .490 boost valve (part # 4L60E-LB1 for your year) which will slightly tighten shifts and increase the max line pressure, both of which reduce wear. Its only about $22 and relatively easy to install - you only need to drop the pan and with snap ring pliers swap the stock valve for the new one.

awesome that sounds affordable and easy

now I just need to make the decision on what yank stall the 3600 or the 4000 I do 50% highway an 50% city driving any ideas on what would suit me best ?

mrvedit

With 50% city driving I would go with the lower 3600 stall and be sure to install a big cooler.

I have 3.73 gears

With 55k I wouldn't worry about it, just keep it cool and let it eat. A 3600 stall with 3.73s is a good combo

He means a BIG cooler^^^^. Don't go with a tube and fin cooler

Why not? I've run a big tube and fin style cooler on the radiator for years with my ss3600 with no problems. I'm switching to a plate style cooler tho to run a braided -6an line setup.
