Thread: Clutches for 4T65E-HD rebuild: BW, Raybestos, or Alto Red Eagle (or other)?

We sell the parts you need I'll have Dave answer the questions you have but here is a link to our parts page. 4T65E Parts

All of the kits that I use are generally Transtec gasket kits or sometimes Toledo Trans gasket kits which are pretty typically OE replacement kits. I only use OE Borg Warner replacement clutches. They last the longest and give the best overall shift feel for normal driving. I have torn many 100K+ mile transmissions apart and the clutches still look like new, that speaks for itself. Most burnt clutch problems are because of a leak in the system, bad malfunctioning accumulator system, bad EPC, incorrect tune. With proper modifications the BWs hold up great on modded cars. There are other options just like you have found, Alto is a good clutch and Im not a huge fan of Raybestos clutches other than the Z-packs for 3rd in this trans but it is money you can save for other stuff. I well a complete master kit with BW frictions for $159.95 . Keep in mind a master kit does not include bands and arent part of any master kit unless they were added to it and its not always necessary to replace them but you wont know until the trans is apart.

Pretty typical except for third, must have got used a lot under WOT and was all stock! Your 4th steels are also very common and a reason I dont like Raybestos clutches especially in that area. A few years ago BW changed the design of them and added a lot more grooves to them. This keeps more fluid on the clutch as it is a lube problem that is causing the "leapard spots" on the steels and you dont see the problem near as much on the newer trans's

Trannyman, thanks much for the info.

Crazy question, but if I post pics of my bands, could you tell me if they are OK?
Is there a thickness spec, maybe?

The bands are going to be burnt or they arent, they really dont wear and if good you will still see the ink printing in the fiber. More often then not the band isnt burnt BUT where the apply lugs are brazed on they will break or tear the braze off on higher mileage bands. Carefully inspect the brazed area and look for cracks, if in question replace them! The manual 1-2 coast band is a coin toss. Honestly the band doesnt get used unless you pull the shifter into 2 or 1, and you shouldnt do that unless you need it for engine breaking, NOT manual WOT shifting! If that band is slightly burnt or has a dark line in it then I wouldnt worry about it, but they are pretty cheap if you would rather replace it. I always bend the new ones open a bit to prevent drag which will also cause the dark line and can also slow the car down at the track

Holy cow Trannyman, you really need like a booklet or something that has all these wonderful rebuild tips. By golly I would pay for the thing. Even some videos, Id have my checkbook out pen in hand just waiting for you to tell me a price.

How am I supposed to keep track of all this stuff, LOL

LOL thats what the forums are for of course!
