Nitrous on the 4L60E Finally getting my money situation straight after buying a new truck in October of 06. Ready to keep modding my 2000 WS6. about to go with a VIG3200 Transgo package and Trans cooler. Really wanting to add nitrous just a 100-125 shot prob a HSWwet. gonna do all the safety features like window,heater,pressure safety switch,etc.(prob set window for 200rpms before shift)But Im really worried about the tranny going out, should I be ok, or should I not spray the 4l60e.I hear around 400rwhp is the limit Id probably be around 425rwhp give or take on the spray with pretty much all bolt ons and 3:73s.Also how would a full dynotune affect my shift points with the stall would they raise them a few hundred rpms cuz I dont think that would be good on the trans with the spray.
i've been spraying my 4l60e for the last 2 years. once i put in the converter i had to have the tranny shift points lowered and rev limiter raised. just make sure you get a window switch and set it for 5800 shut off.

If you're not spraying through the shifts then it should last awhile. The keys to making these transmissions last is a tranny cooler, keeping shift points reasonable (6500 or less), not going into OD at WOT and not spraying through shifts.
If you ever want to spray through the shifts or rev higher then you might want to look at FLT, Performabuilt or Rossler for a heavy duty 4L60E.

I started with a brand new 4L60E put in a transgo HD-2 a Yank 3600 and A B&M supercooler. I make 491RWHP and shut the spray off 100RPM before my 6300rpm shift point. Truck weighs 3850LBS and 60 foots 1.57
I have 36 track passes on this setup with no signs of slippage so far. Every thing seems to be holding up well.

Sounds good guys dont think I will need the shift points raised much with the stock head and cam will have the window switch set with first gear lock out and cut off around 200rpms before the shift, really with the window the nitrous would only be used through the 2nd to 3rd shift wont make it to 4th b4 the end of the 1/4mile.Any idea how high the shift points are usely raised with a bolt on, 3:73, 3200stalled car. I would think over 6500?

don't spray through shifts, put on a tranny cooler and keep your shift points under 6,000 rpm's and it should last a while. however, nitrous is incredibly deadly to any transmission because it hits it ALL AT ONCE. it's kind of like being punched in the face out of nowhere. whatever happens, expect tranny problems eventually because it was never designed for this punishment.

as long as you arent blowing through the converter (you shouldnt be) have at it and stop spraying before the shift as said. My trans builder told me to throw whatever at it I wanted. That's what it was built for.
I hate to be the grim reaper but my car was running 12.0's average on heads and cam and drag radials on many many passes.
Then....I added a 150 shot of N20 with a window switch shifting at 6200rpm....
The trans did not go boom but it quit wanting to 3/4 shift at WOT after about the 2nd n20 pass.

Humanoid you were prob around 400rwhp with that head and cam right?Sounds like ur trans held up to that ok.Im sure on spray you were over 500rwhp thats what killed ur trans right? I am pretty scared that the my trans is gonna go out but if it does I should have enough to get a new trans.Im also not gonna spray it alot just make a run it at the track on bottle and off a few times to get my time.Dont see me spraying much on the street,plus its not my Daily.
Stang slayer, Why do you think ur trans went out?cause of the stall or power you were making or ur driving habit?
