Applications

Tech Note 1: 1973-earlier Turbo 400 Transmissions
Most if not all early Turbo 400 transmissions (prior to 1973) have 27 spline output shafts. Later models use 32 spline shafts.

Tech Note 2: Worn Clutch Teeth
The most common wear issue with NP205 input shafts is worn clutch teeth. It does not take much wear on the input shaft and sliding clutch collar teeth for the transfer case to "jump" out of high range. If your input shaft has significant wear on the clutch teeth, replace it and the sliding collar.

Tech Note 3: Inspect for Wear
NP205 Input Shafts may also have damaging wear on other locations. Input shaft with significant wear that can be felt with your fingernail should be replaced with a new shaft along with the matching component. Look for wear at these locations:
Rear Bearing Pilot: Indentations from the needle rollers that fit in the front of the rear output shaft
Helical Gear Teeth: If run short of oil, teeth will show temperature discoloration and/or visible wear
Input Splines: Visible wear on the splines is usually caused by lack of lubrication
