hey everyone, i just got a brand new yank ss3600 converter installed in my otherwise stock 4l60E trans. Its a '98 transam making about 362hp to the wheels. stock cam. The tuning for everything has been done by Frost and its all perfect except for one thing: the torque converter tends to slip a bit under moderate throttle at highway speeds like if i want to pass someone but not totally gun it i can feel the clutch partially disengage but not totally and it never ever did this with the stock converter even with heavy throttle the lockup clutch would hold.
So far with Frost, we changed the misfire tables to 32727, set the TCC duty to 100% max and 98% min, and eliminated lockup all together in 3rd gear. the problem is still there though and not too sure what is wrong.
Can someone maybe explain to me in the Force Motor Current table, the horizontal axis which starts at 0 and goes up in incriments of 6 until it reaches 96. For each incriment, what would it represent in terms of throttle position? like would 12 on the horizontal axis also be close to 12% throttle or no?
I figure maybe if i lower the numbers (increase pressure) in the low throttle situations between 0 and 30% TPS (first 5 columns???) maybe i can eliminate tcc slip but not affect transmission performance/reliability at WOT. If I can accomplish this then i can set the lockup clutch to unlock at anything more than 30% throttle but at least not be slipping anymore.
Ive had a dakota r/t with a 3800 Viper converter and I would lock that at WOT to get better mph in the quarter mile and so that I wouldnt run out of gear (4.56's) but i guess WOT lockup is just not possible with the stock 4l60E?
