Yank 4000SS installed and hitting rev limiter
Yank 4000SS installed and hitting rev limiter Looking for some input on what to adjust in my tune (trans tables) after installing a Yank 4000SS. I previously had a Yank PY3400 and had no problems but now the 2-3 shift is going beyond my set point (6100). I have tried lowering to 5800 RPM and it is still hitting my limiter (7000). I have NEW (less than 500 miles) FLT Level 5 4L65E in the car. Worked great before the swap. The converter is Brand NEW and has been in for 75miles.
Also, do most lock -up the clutch in gears other than 4th for normal driving? This thing is loose driving around town. I am not sure I like the constant 2500-2900 in 3rd (unlocked) until I hit about 45-47mph when fourth comes in and it locks.
Car is a 2000 SS with 3.70 gears.
I have attached my tune. I am using HP Tuners.
Thanks in advance.

Shouldn't you not beat on a brand new converter until you put like 500mi of break in on it? I would be less concerned about then the hitting the rev lim then ruining a brand new converter.
Your WOT MPH shift points seem to be high compared to to other 3.73 geared cars I've tuned. Try lowering them.
Your TCC lock up tables have been edited to lock up only in OD (4th).

I was searching around on HP Tuners site and I think you are right! I compared mine to a few others with 3.73's and my 2-3 is higher by a bunch, I was overlooking the mph setting and just looking at the RPM. I will try this tomorrow. Learned several other things there too while looking at some proven trans table settings. I will also try locking the clutch in 3rd at moderate speed and loads, this should help a bunch with the driveability.
