Re: LQ4/4L80E torque converter

I have recently been using RoadRunner converters. If you call Jim there and tell him Shaun Liddy sent you he will for sure treat you right.

I am a big fan of BIG converters especially since you have a lock up trans (talking 4,500-5,000rpm, last one actually went to 6,200 on the N20 kit) but... That requires you to have an awesome tuner or the ability to tune yourself and take the time to do it right.

Oh, and a 4,500-5,000 stall would NOT be good for towing. It's mainly an issue with 1st as once you are in 2nd-4rth and the verter is locked, a good tripple disk will not slip even with a trailer behind you going up hill. But the time you are in first will heat up the trans.

No doubt a 4,500-5,000 rpm converter would wake it up out of the hole, but I would probably tell you to keep it to about 3,200 max with towing in mind. but call Jim, and tell him what you are doing.
