Want me to just start a new thread incase it needs to be deleted?
I'm not going to alienate the other 3. If they want to speak of their problem, then so be it.
Here's what I know--
I've got a 450hp J-mod, Mechanical diode, and upgraded clutchpacks (and some other minor things) in my transmission; as well as a 9.5" 3800 stall single plate converter that I am very fond of.
After the transmission's install, there became a delay after the 1-2 and 2-3 shift. It lasts about .5 secconds, and feels the same as hitting the 3000rpm limiter in 4th. On a datalog, it shows "1.07 million" degrees of timing, which is obviously a false reading.
So, During this delay, where the timing jumps (in some direction), the torque converter only stalls at 3700, and the car really doesn't accelerate. Obviously, the motor isn't making as much torque as before.
A tune DOES fix this completely; however, in both of my friend's cars that have been J-modded according to the tech articles, the problem isn't there to start with.
I don't know if anything is really electrically "Wrong" or just not what the computer is used to seeing. That kindof steps into the "proprietary modifications" relm I think. Maybee some of the sensors in the transmissions are sending a revised signal to the computer? This is where I'm not completely clear on what's going on.
So the problem is that the stock computer freaks out, and throws a red flag right after the shift. What I don't understand is why this happens with a fully built transmission and torque converter, and not a car with a marauder converter, and the valvebody mods in Jerry's article.
Thanks for taking the time to consider what's up with this thing.
