turbotom Team Bute Donating Members 1,550 Member For: 21y 9m 7d Gender: Male Location: Adelaide Posted 19/07/06 12:08 PM Share Posted 19/07/06 12:08 PM OK.... so my band did not break as I thought.... but the kevlar lining was completely gone. Too much slippage caused frictional heat, which eventually caused metal to metal scoring of the drum surface. Here's a couple of pics of the 2-4 band which lost its lining, and the resultant drum damage. The drum could have been machined/linished smooth, but I've opted for a new replacement.too much applied torque is the culprit.... around 800+ Nm @ 3000 rpm and this was still with street tyres. More clamping force for the band is required.... or I might have to regrettably reduce torque below 3500 rpm for reliability Link to comment https://www.fordxr6turbo.com/forum/topic/26744-4-speed-auto/page/3/#findComment-409185 Share on other sites More sharing options...

If your gearbox builder is just doing it via the S5 solenoid, the band burning will occur prematurely. Mod the box via elimating the S5 completly takes it a step further with ultimate shifts and prolongs the life of this band. See what you builder is doing. Not all boxes are modded the same.

rjs Donating Members 525 Member For: 22y 3m 27d Location: Sydney Posted 04/08/06 08:27 AM Share Posted 04/08/06 08:27 AM My box went some time ago, lost 2nd and 4th gear. I can still put it in reverse but other than that, 1st and 3rd and still holding up. I am getting a rebuild done in a weeks time through C and V and will warranty the box for 12 months. Hopefully this rebuild should last. Link to comment https://www.fordxr6turbo.com/forum/topic/26744-4-speed-auto/page/3/#findComment-416747 Share on other sites More sharing options...
