Romer Posted March 28, 2017 Report Share Posted March 28, 2017 Hey guys, just wanted to ask for some experience In the newer cars now days (2000's) that have Auto trans with the sequential shifter or "Sport" "Manual" option, would it be a good idea to bring it to the track? endurance racing? overheating trans? Just want to know what thoughts and experience you guys have with those type of automatic transmissions thanks Romer Quote Link to comment Share on other sites More sharing options...
3G Posted March 28, 2017 Report Share Posted March 28, 2017 Full manual valve body on a older th350 or similar maybe. Newer electrionic controlled trany in "manual" operation No NO NO! they suck bigtime. My experience with them says to leave it in drive, the long delays and it still auto shifting at redline or bog is so annoying its not worth it.

Hi_Im_Will Posted March 28, 2017 Report Share Posted March 28, 2017 Tow/Haul mode on my F250 does a pretty damn good job of picking gears around Gingerman and Grattan. Never got warm either, at least not before I ran out of brakes. Got some PFCs on there now, so will have to try again this year and see if I can get the trans hot.

skierman64 Posted March 28, 2017 Report Share Posted March 28, 2017 I've seen both 3 series and 5 series BMW automatics do pretty well in holding up to the rigors of racing. There was a 540 that used to race at Road America that seemed to have not have any trans issues, and Bruce Transporters used to run a 3 series automatic. 1 Quote Link to comment Share on other sites More sharing options...
JBgotM Posted March 28, 2017 Report Share Posted March 28, 2017 (edited) At one point in time, you either had a manual, or a hydraulic automatic with torque converter. The old systems did what you told them to. I used to run an auto where I manually worked the lever. If you truly are controlling the transmission directly, then you may be ok. The systems now are much more diverse, and they have different traits or reasons they may or may not work. If you are around the design of the more modern control systems, you will hear the word "request" being used. The user "requests" for the vehicle to do something. The vehicle looks at all it's parameters and how it was taught to behave, then it responds... or doesn't I would be very weary of a system that you have not studied how it works and understand it's trade-offs.

JB's posts describe new car electronic systems well. They suck! When you turn the key to start, or turn your blower fan for the heater on, in the old days, your starter, or the blower fan engaged IMMEDIATELY when you turned the key, or flipped the switch. Now, you are just making a suggestion that you want to start the car, or turn on the fan. The computer thinks about it for a few seconds, then does what you want it to do. A lot of OEM's now come with paddle shifters on the steering wheel. I made sure I got that feature on my last lease car, anticipating a lot of fun. Turned out to be a joke. 1 Quote Link to comment Share on other sites More sharing options...
Team Infiniti Posted March 28, 2017 Report Share Posted March 28, 2017 (edited) If its a conventional rather than dual clutch, big cooler, syn fluid, temp gauge, shift improver kit, put it in OD and forget it.

Romer Posted April 3, 2017 Author Report Share Posted April 3, 2017 Awesome, thanks for all the info and help guys. After reading and thinking about it we might stay with the good old manual transmission. Thanks again everyone Romer 1 Quote Link to comment Share on other sites More sharing options...
