  1. 6.5L Diesel Engine
    I have a 1996 and a half chevy 6.5 turbo diesel with a 4l80e that I have been having issues with. I've exhausted every effort and now I'm onto rebuilding the transmission, the issue is that it is a 96 ½ and all the year sensitive parts I have had to replace are either only for that half year or...

  4. 4L80/85E Transmissions. 6L90 Transmission
    こんにちはみんな! 最初の問題は、地面が平らであるにもかかわらず、ブレーキを解除したときに地面が前進しなかったことでした。 アクセルを踏むと進みます。 そして、私は約60マイル走りました。 そして突然、4速にシフトアップするとすぐにブレーキをかけたように減速しました。 手動で3速にシフトダウンするとブレーキが解除されます。 その他の症状は、シフトレバーの位置が1、2でも3速にシフトします。 また、DからRにシフトすると、エンゲージメントが約5秒間遅れます。 このトランスミッションは約125000マイルで再構築され、現在の走行距離は約135000マイルです。...

    I have a stock LLY with obviously the allison tranny. I noticed the other day that from a complete stop there is a weird thump when I hit the pedal to get moving. Nothing abrupt but it is noticable. There is no tuner on the truck and has never been used to pull large amounts of weight. Has...
