Auto Tranny Build Up Guide
i got my tranny fully built aka "Bulletproofed" by level ten.. im going to tell u it cost ALOT. expect to pay 5+ g's with shipping. the auto shifts AT redline.. to change the shiftpoints the greddy ultimate is needed.

If you just lay the pedal down it wont hit redline then shift, it shifts sometime before that point. How could I change the point in which it shifts? It would be pointless to have head work done allowing it to mechanically rev to 7500rpms then get tuning done so the rev limiter is also raised to 7500 rpms only to have the autotrans shift on its own at 5400rpms(estimated).

but thanks SoFloTC and ChitownTT for the additional info.
soflotc did you feel a differance in power, that was lost in all auto transmissions? im also thinking of upgradeing my trans but , will i feel a differance, im running 12psi,s/c meth injection,full exhaust , brian cams stage 2,and cold intake with e-manage ult.
I Posted this in the IPT Thread, but figured might as well here too..
Not to Doubt anyone, or cause any problems, but here's the Info straight from IPT.
"It is hard to say an actual horsepower number,many variables come into play such as how the power is being made.(turbo,nitrous,all motor) and how the vehicle is being used,(drag,road race,drift,street or a combination of all of them)
That being said,if the transmission was rebuilt using our rebuild kit,valve body upgrade and torque converter the transmission should have about 35-40% more holding power,if the transmission was sent here and we did the in-house build (cryo,additional clutches,reworked pump,etc,etc.) the transmission would be as bullet proof as possible,and have over 70% more holding power.
Hope this kind of answers your question,if you have any other questions about the build please feel free to give me a call here at the shop 1-866-82-TRANS (toll free)"
So, with that being said.. If our Trannies start to Slip around what, 240whp? Do the Math and it comes out to being a MAX of 312whp that we can hold. (240x1.3) which is good enough for someone like me who just wants to hit that Big 300.
Sure, being able to hold 400whp is much nicer, I don't really have, nor would want to, drop that kind of Cash for a FULL Re-Build.
I think I'll stick with the Valve Body, Torque Converter, and Re-Build Kit, and get close to that 300whp whenever I Turbo.

Well my levelten tranny was to much of a hassle to work with so im swapping and going manual lmao.. we couldnt change the shiftpoints with the ultimate for soem reason and then levelten told me i needed to buy there special transmission ems? i was like well ____ that you should have told me that in the first place. so w.e im sending the tranny back to them to "refresh" it incase any damage was done to it (most likely not) and i will be selling the FULLY built auto.
its holding 15 lbs of boost... but the thing is it wasnt shifting at redline because i didnt buy leveltens special EMS thingy they said.. so i was like ____ it.. its built for 400-450 BHP.. im expecting to surpass that power anyway so im just swapping to manual.
