What do you expect to see with a video? I have 4.10's and a supercharger making 660 rwhp. I drive the car from Atlanta to Houston, Dallas, Cordova, Bristol, Richmond, Orlando, Gainesville, etc. for the FFW events. I have driven over 800 miles in a day with absolutely no problems. The car runs low 10's and traps at 135 in 3rd gear. I cruise around 73 mph at 2800 rpm on the Interstate. Anything less than 4.10's is a waste of time and money.
4.10's in an Auto Video?

Do you have a tranny cooler and what is your opinion on running the engine at 2,600 rpms Stock engine I mean how do you know what rpm it is hurting the engine???
So I could hold the rpms at 3500 for hours and not hurt it with a tranny cooler. And I am Mechanically Inclined Could I install my own tranny cooler.

That's what I'd like to see. How hot does the transmission fluid get when you hold it at 3000+ RPM for an extended period. I know the temp shoots up without a cooler.joshheat25 said:
I thought you had a trans fluid temp gauge, josh.

He (we) are looking at getting 4.10s in our auto tranny car. My normal 80-85 mph highway driving will take me over 3000 RPM.jimfitzgerald said:
I cruise at 3000 rpms (80mph) all the time no issues, no tranny cooler. Correct me if I'm wrong but the tranny fluid gets hot primary when the stall is slipping and when shifting. When its locked up in OD I dont see why running a slightly higher rpm will make any difference? (I dont claim to have much knowledge about trannys tho!!

Do you have a way to display your transmission fluid temperature? If the temp goes up to 250-300, you would't know and would not report any issues. It's true that slipping causes heat. Spinning at 3000+ RPM seems to heat it up too. But that's based on one test I did. I want to see if other get the same results.007 said:I cruise at 3000 rpms (80mph) all the time no issues, no tranny cooler.

Does your trans cooler totally bypass the factory cooler in the radiator? Or is it inline with it?YtnGT said:
So It is a Very Good Idea to Get a Trans Cooler with 4.10's! And Running your engine at 2,600 to 3,000 rpms for an extended period of time will not put wear and tear on your engine!
So would running my engine at 2,600 to 2,800 rpms put an extra wear and tear on the engine! If I get gears I will get the trans cooler!
is that a hint not to get them! and also no one has answered my question about wearing the engine. ... I know a supercharger or any forced induction will wear the life of an engine down but what about running too high of rpms on the highway???
