Engine stalls when shifted to R position/mode from N position/mode

Probable cause(s)

• Engine output low
• Forward clutch defective
• Planetary carrier assembly worn or damaged
• Thrust needle bearing or thrust washer on planetary carrier assembly seized, worn, or damaged
• Torque converter assembly defective
• Torque converter ring gear worn or damaged
• Transmission assembly and drive plate installation defective

Notes 

• Adjust the engine output.
• Inspect the clearance between the forward clutch end-plate and the top disc . If the clearance is out of tolerance, replace the input shaft assembly.
• Check the planetary carrier assembly for wear and damage. If the planetary carrier assembly is worn or damaged, replace it and also check the planetary carrier pinion gears, the reverse brake, and the drive pulley shaft splines for wear and damage.
• Check the thrust needle bearing and the thrust washer on the planetary carrier assembly for seize, wear, and damage. If the thrust needle bearing or the thrust washer are seized, worn, or damaged, replace them and adjust the clearance with the thrust shim.
• Inspect the torque converter assembly for wear and damage. If the torque converter assembly is worn or damaged, replace it as an assembly .
