torque converter lock up mod
Ok boys,
So I give a buddy of mine a CPS spare to carry in his truck. Because we are friends, I did not expect any repayment etc. Well he gets this torque converter lock up kit from SPdiesel. He has apparently decided he has no use for it and wants to give it to me. I really do not know anything about the mod and would like some info. Did a search and found tons of talk aboutit sounds cool, don't leave it locked up under 30 mph, not in first gear, the tranny is already locked in o/d, etc. But really what are the benefits from this mod? Anything I should avoid? Do I really need it? I see that it helps with towing I tow a 35ft 5er, but how does it really help with towing? Need the info give it to me.

Maybe I am just not getting it. I down shift prior to starting a steep decent, and haven't had any issues. The only reason I am really curious is I obviously like modding the truck but the tranny I am a little leary of just because I really know nothing about them. I do not want to damage or cause premature failure of the tranny. If the mod will really benefit me and even help the tranny I am interested if not, I will leave it be.
Does this mod aide in pulling at all up hill or on flat surfaces. Here again I have had no issues but, anytime you can improve towing it is a good thing esp when pulling steep or long grades. Thanks for your help T of G

I use mine all the time in town, stop light driving, where you slow down to about 20 mph but never really stop, I like it alot better, truck feels smoother, the TC would never lock below 35 or so, so the engine was always revving way up, then idle, rev up, idle. with it locked, it is just like a manuel. ya fallow me on this???
I also use it for slow speed towing also, where I am only in 2nd gear, but the rpm's are up. lock it to keep tranny temp down. a locked converter makes alot less heat them an unlocked one.
same as TOG said, down hill, lock it, OD off. can go down 9% grades empty and never touch the brakes.
its also fun to lock it at 10 MPH and stand on it. watch the smoke roll.
