Chevyss Posted January 11, 2009 Share Posted January 11, 2009 Wish I'd known about this before I installed a 7004R. It sounds like it will be a great addition to the crate motors. OH WELL!! See how the 7004R holds up. Thanks for the info Quote Link to comment Share on other sites More sharing options...

monte70car Posted January 11, 2009 Share Posted January 11, 2009 i saw a 4l65e over on the bowtie overdrive board that is $2000 and you dont need a computer to control the shifts. Quote Link to comment Share on other sites More sharing options...
Paul Bell Posted January 11, 2009 Author Share Posted January 11, 2009 The E in 4L65E means it's computer controlled. You have a link to the bowtie overdrive board? Quote Link to comment Share on other sites More sharing options...

monte70car Posted January 11, 2009 Share Posted January 11, 2009 paul this is all bowtie overdrive has on the 4l65e 4l65e Quote Link to comment Share on other sites More sharing options...
Paul Bell Posted January 11, 2009 Author Share Posted January 11, 2009 Monte70car, I saw that. Being that a 4L60E is based on a 700, the hard parts fit the non-computer controlled 700 housing. It's a fairly common swap. Incidently, the 1993 4L60 transmissions weren't computer controlled. Yup, the 4L65 is a pretty stout unit. They blow up less often than the 4L60 units. For any sort of performance or hard driving, it's just a matter of time before they go south. The TH400 or 4L80E/4L85E is the way to go. The purpose of my posting info about the new GM SuperMatic transmission is to get that level of strength from a performance transmission shop, you'd need to spend five grand. This is a way to save some bucks. Quote Link to comment Share on other sites More sharing options...
overdrive Posted January 12, 2009 Share Posted January 12, 2009 Does anyone make a good overdrive to modify the TH400? Quote Link to comment Share on other sites More sharing options...

680HPStroker Posted January 12, 2009 Share Posted January 12, 2009 I'm waiting for GMPP to bring out the 6L80E as part of their line up. It's currently being used in trucks, G8 GT's, Corvette's, the new Camaro, and probably more. From what I've seen of the internals it looks like it can hold as much power as a 4L80E and a that tranny holds 900HP in stock trim. Quote Link to comment Share on other sites More sharing options...
Paul Bell Posted January 14, 2009 Author Share Posted January 14, 2009 I'm not sure if there's any advantage to going to the six-speed. The top gear ratios are pretty close to a four-speed. A six-speed allows the engine to operate in a narrower range. Quote Link to comment Share on other sites More sharing options...
RARE MC Posted February 26, 2009 Share Posted February 26, 2009 I am ready to do something. Not happy with 4,000 rpm at 85 mph. LS-6 454, stock cam, 3.31, 275/60/15, TH400. I'm thinking GV or 4L85-E. I'd hate to have to pound my floor. But I can't see that nearly as much as I do the inverse relationship between my tach and gas gauge.
