Just put my third seal in and it leaked again. This time I put in UV dye and the results show a leak from the main inner primary oil seal. This seal is PN 12052A and seems to not have a good fit around the transmission shaft. All bearings are tight and no leakage from any other spots. I wonder if this seal is really the right one???

 

Search M1148 Service Bulletin. It looks like your seal is in upside down.

 

you are correct....thank you soooooooooo much!!!!!!!!!!!!!!!!!!!!!
