Converter Lock-Up Problems
Got my car dyno tuned today with SCT software. Numbers were 247rwhp and 286rwtq.
Horsepower mods are:
MAC 2.5" Pro-Dumps
C&L Upper Inlet Pipe and K&N Filter System
UPR Catted X-Pipe
BBK Shorty Headers
Ported & Polished Plenum and Throttle Body (70mm FRPP) + Steeda Plate
1/2" Billet Plenum Spacer
4.10s
j-mod Valvebody
Atlantic Coast Converters 3200 Stall Billet Converter
TCI Deep Aluminum Trans Pan (+2 quarts)
Steeda Trans Cooler
Steeda Underdrive Pulleys
180* Thermostat
Car weighs 3300 lbs. (+ driver)
With passenger seat and front sway bar removed, car weighs 3250 lbs
Problem was, when commanded to stay locked, the converter is unlocking in third at around 5250. Maybe this is in anticipation of the shift into 4th gear (O/D) but we had 4th gear locked out. Looking at the dyno graph you can see what I am talking about. Has anyone experienced this? Recommendations???
