[TSHACK]

I was wondering if anyone uses automatic transmissions on road courses. I remeber there was a few autoxers that did several years ago. It's not that I don't want to go to a T5 or even T56, I'm just doing the bad thing I do & think too much about stuff! (IMG:http://www.frrax.com/rrforum/style_emoticons/default/dry.gif) (IMG:http://www.frrax.com/rrforum/style_emoticons/default/rolleyes.gif) I even have a Hurst shifted T10 with everthing for the 74 camaro.

Stan is that a 4 speed, Or did they start making 5 speeds. I remember looking inside of a jerico once, Wow I thought my brother inlaw's rock crusher (M22) was beefy.

I can only afford a 4 speed. The 5 speeds are about 6k$ IIRC.

I felt such a pussy being the only guy at the track with an auto. I might have overcompensated with the Jerico, but it's fun.

I was sick of the sloppyness of the auto but mostly the leaking. 60 lb weight reduction is cool too.

Scott (Roadracetransam) has ran an 4L60E for quite some time and had good results (5th at nationals and 2nd or 3rd in is region in TTB). Maybe he'll chime in.



ERVRCG, interesting info about the calcs. I guess that confirms my theory.

Are you using my name in vain again?
So I had the 4L60E with the E part removed. I got it built up fairly bullet proof, extra cluch packs, steel sleeve, manual shift kit, all the electronics removed. I also had a rachet shifter and a heavy duty torque converter. The converter was needed for the loopey cam. Also I put 2 oil coolers in series, each 11"X18", in front of the radiator. Even with that much cooling I reached 300 degrees by the end of the sessions. Fluid changes after every other event. I only had the "auto drift" in 4th gear. With my 3.23 gearing I only grabbed 4th in the MidOhio backstraight (not a problem since it was in a straight line) and CalSpeedway in the oval, (bit conserning) Otherwise it held the gears and RPM's the same as a manual. Shifted when I hit the rachet up or down, never by it's self. Sounded like dragster, wide open throttle shifts.
I moved on to the T56 (still sitting on the garage floor) because I plan on moving to AI in 2009. Only syncromesh trannies alowed. I could have run it in AIX, I just don't have the $ to do that.
It is doable. Would I do it again? Probably not, but it was fun while I had it.
There was another Auto in TT here in SoCal. '71 Trans Am with a TH400 reverse manual valvebody. He was TTD champ with that car in '05, '06. Blew the motor in '07 and got a 2001 ex-SCCA Firebird with a manual.
