BXX Posted June 17, 2011 Report Share Posted June 17, 2011 98 Grand Prix GT, this should help ya:thumbsup: Of course it does kinda vary here and there, what vehicle did you get your PCM from? Quote Link to comment Share on other sites More sharing options...
redynscire Posted June 17, 2011 Author Report Share Posted June 17, 2011 Got my pcm from a 02' GTP. Also, my converter is locking at 28mph..does it under light throttle. Likes to lockup at 30 when i start going up a hill. Or any kind of load really. Quote Link to comment Share on other sites More sharing options...
Addicted to eaton Posted June 17, 2011 Report Share Posted June 17, 2011 thats a little to soon lol. unless ur giving it no gas. Quote Link to comment Share on other sites More sharing options...
redynscire Posted June 17, 2011 Author Report Share Posted June 17, 2011 i thought it was a little soon.. No, I am on the gas. Say enough to hold your speed flat ground. Or giving it a little more gas for an upcoming hill. I am just trying to figure out if this was off, or if it is bad for the converter to cycle so much at that low of speed. Plus it lugs the hell outta the motor. This is my DD right now, think it will be safe to drive untill i can get it tuned? Or should i try and disable the TC from the brake switch? Or just park it till it can be tuned? Does this sound like an issue from having a GT trans and using a stock GTP pcm? Quote Link to comment Share on other sites More sharing options...
AL Posted June 17, 2011 Report Share Posted June 17, 2011 That sounds right actually, its 3rd gear lock Quote Link to comment Share on other sites More sharing options...
redynscire Posted June 17, 2011 Author Report Share Posted June 17, 2011 Sounds right? so its normal for the torque converter to cycle on/off on/off at 30mph while lightly on and off the gas? Seems like alot of cycling...locked....30mph....slight hill....bog.......let off gas..unlock..get on gas.... get to the top of the hill...let off the gas..unlock.....same condition on flat ground with the light throttle and letting off. i would think this should be in the 40 to 50mph range.

Addicted to eaton Posted June 17, 2011 Report Share Posted June 17, 2011 no that is Not normal. it should lock and unlock alot on a hill at slower speed though. most every 3800 i have seen hunts for the tq... ill just come up and ride in the car and tell you if its normal or not i ahve had 5-6 l67 cars and rode in 40-50 Quote Link to comment Share on other sites More sharing options...
urbex Posted June 17, 2011 Report Share Posted June 17, 2011 Maybe I'm reading it wrong, but doesn't the chart Bob posted show it locks up at 30mph? Quote Link to comment Share on other sites More sharing options...
redynscire Posted June 17, 2011 Author Report Share Posted June 17, 2011 (edited) no that is Not normal. it should lock and unlock alot on a hill at slower speed though. most every 3800 i have seen hunts for the tq... ill just come up and ride in the car and tell you if its normal or not i ahve had 5-6 l67 cars and rode in 40-50 that would be great. i was trying to get reptile to drive it..he seems busy though. i can meet u half way...car does alright on the highway. say in kearney? or if you feel like a drive come on out.. i may have some free time this weekend..just let me know every 3800 you have seen hunts for the tq.. on a hill? what about engage at the bottom of a hill and wants to stay engaged up the hill "at low speeds" bogs or lugs the motor and it wont disengage up that hill unless you let off the gas?? then get back on the gas a little more so it wont lockup again up that hill.. shouldnt it unlock on its own when the motor starts bogging down?

redynscire Posted June 17, 2011 Author Report Share Posted June 17, 2011 Maybe I'm reading it wrong, but doesn't the chart Bob posted show it locks up at 30mph? i looked at that and was thinking the same thing....lockup at around 1/8 pedal, 30mph Quote Link to comment Share on other sites More sharing options...
