yeah,im going to put the console and the gaitor back on tonight then take it out to see,it seems to be doing it in 3rd,4th and 5th mostly,maybe because the box isnt under much load when in 5th it is doing it the most.if it needs a rebuil is cts the place to go?i think i seen somewhere he rebuilds them for £400,is that right?i dont want an exchange box as i know mine isnt knackered and simply worn out in all areas.cheers,lee
