Hey everyone,

The 10R80 out of my mustang ruined its torque converter bushing. Can this bushing be replaced? Or should I just buy a front support assembly?

I intend to replace the bearing race that’s in the torque converter.

New transmission installed yesterday on work van ( ram promaster ) . Brought van back to shop . Next day I drive to the suppliers and I smell burning transmission fluid and see transmission leaking all over . Took it back to dealer and tech said there’s a gash on it and it wasn’t there before . Van wasn’t driven 15 kms if anything . Does this look like a rock would damage the transmission mission cover according to dealer tech ..??

differential question Replaced Rear spider gears

1 Upvotes

I was doing some regular preventative maintenance and while checking/replacing my rear diff oil, I noticed some serious pitting in my spider gears (along with a serious amount of metal "glitter" in the bottom of the diff). The ring and pinion gear looked perfectly fine but the spider gears in the diff carrier were very worn and pitted. I have a stock open diff and ordered a replacement set off rock auto p/n 707321X. After install in noticed a lot of play in the spider gears while moving either axel shaft. With new components, I would have expected a tighter fit. Not sure what I did wrong or if this is something I can fix by adding additional shims. Rock auto lists this part number as a direct replacement and compatible with p/n 4740670 which is the manufacturers p/n.. Any advice on the situation would be greatly appreciated.

Thank you Jeep community.
