When installing the output shaft yoke on any THM 700-R4 transmission, be certain to do the following:
1.
Grease the sealing lip on the case extension oil seal assembly.
2.
Clean all corrosion, dirt, nicks, or burrs off the output shaft yoke.
3.
Use care when installing the yoke, so that it doesn't cut or tear the case extension oil seal assembly.
If these items are not performed, wear may be experienced on the oil seal assembly and a leak may result.
