Road Test

  1. Before testing, make sure fluid level is correct and all linkage adjustments are correct. Transmission should shift at approximate speeds shown in Fig 1 charts. Speeds may vary due to model, tire size and axle ratio. The important factor is that all shifts should be smooth, with no slipping or engine racing.
  2. Slipping or engine racing during shifts usually indicates clutch or brake slipping problems. Unless an obvious condition exists, transmission should never be disassembled until hydraulic pressure tests have been performed.
