4L60E converter question
4L60E converter question Need help with what stall I should use on my 4L60E. It's a stock 5.3 with BTR228R cam, LS6 intake, and upgraded springs. Texas Speed told me that I should use a 3600, but others are trying to tell me that is to high. Suggestions please. It's a 95 Firebird and for street not strip.

what kind of vehicle ?
Yes,3600,3600-4000 from a 'reputable' converter builder such as CircleD or Yank or a few others. Not from TCI or other 'off the shelf' converters,but a custom build.

I have experience with Yank as I've had an SS3200, SS3600, and currently running a PAS3400. All street driven, will leave the light with slightly more peddle input but not crazy. The biggest difference is when you smash the gas it sits you in your seat. I would call up a few different companies, explain what your wanting to do with you car and have them recommend something, in the end its what your willing to pay.
i think your friends are getting confused between the 95's lt motor & the ls1 motor. ls1's like higher rpm & with your cam i'd definately go with the 3600. the lt motors are better low end torque and like less converter. i went with a 3k hoping i wouldn't have to retune (i read somewhere) wrong i needed a retune so i wish i went with the 3600. when you hit the gas it feels like an extra 100 rwhp thats how awesome a convertor is! downside with my 2:73's i lost like 2 mpg because it takes more gas to get going normal driving.

I loved he SS3600, however it didn't like the abuse that I gave it with having a SC on the car and I've lived on the edge of the max HP level for that converter. I went to the PAS3400 due to the strong recommendation from Dave at Yank, he said it would hold up better for the SC and would live longer at my HP level without having to step up to the Pro Yank Series.

I will just add rear gearing will change how a converter "feels" too.
I recently installed my old t350 and 8" treemaster in my sons malibu.
He has 3.42's , I have 4.30's
That converter in my car drove like the 12" one it came from the factory with 44yrs ago.
In Matt's car, it is "looser" meaning it takes a little more to get it going whereas in my car it would idle down the road.
That said, I had Circle D make me a 245mm 5C triple that should flash to 5k behind my 406 (IF it hooks) and almost feels to tight during normal driving....jump on it and it's just like the 8" converter!
Don't skimp on a converter.

I know it's been a while, but I talked to a local performance shop and they suggested that I go with a 2400 stall because if I go with a higher stall it is going to slip a lot since I am doing most of my driving under regular conditions on the road. I don't need a converter that is built for the strip because I am not going to be doing that. I just need something above stock that is going to work for my setup.
2400 isn't even worth to install. like others said, if it's not a dedicated track or see a lot of track time but mainly cruising then anywhere between a nice tight 3400-3600 stall would be alright for DD use.
What is the reasoning for the higher stall if I am not racing it? Won't the higher stall cause the car to slip under normal driving conditions? I guess never have driven a car with a stall is got me all messed up. I just want to drive it on the street to car cruises. I talked to Circle D and they said to go with a HP278 3000-3200 stall. I have 3.23 gears right now, but will upgrade further down the line to probably a 3.73.

you really have an LS1 dropped into a 95 bird? it's a 5.3 with 3.23 gears. that clears it up. it took an extra k to get there with 2.73's and only an extra 5 with the higher gears. so i should be right in the middle with a 3200?
You just want to drive it on the street to car cruises,then why even bother changing your OEM 1800 stall to a 2400 stall. That 2400 will probably 'slip' more than a good tight 3500-4000 from CircleD or Yank. That 2400 sounds like you're 'cheaping out' because it's an on the shelf item from some place. 3.23s' with a good stall might even change your mind about going to 3.73s',thereby the money spent on a good stall will/would save you the money you would have spent for the gear change.
I drive around town with 3.23s'/Yank SS3600 and it's perfect,drop it in gear from park/neutral and the car starts to creep forward,no excess rpm needed for city driving.

Not trying to cheap out, just want what is best for what I am doing and being able to drive it in the city without a problem. I planned on going with the Circle D converter with 3000-3200 stall, but someone I work with told me to give this shop a call.
