I am having problems with the reverse slipping badly.
I read it could be caused by the J type overdrive (used on the manual tran. M46) not able to release its 450 psi pressure even when turned off.
So I removed the bottom cover and removed the three plugs.
Found broken oil filter, broken relef valve spring and multiple worned out oil seals.
My question is: If I am interested in getting the pressure to release and to see if I can get the reverse to work, how could I make the OD to not build up pressure at all i.e. To disable its function as an OD so it never interferes with the reverse operation. At least that's how I understand it.
Can I just keep the relief valve temporarily out of the system and put everything back together (with a good oil filter)?
I would do this mainly to test that I can get the reverse to work.
If I do not get it to work and I knew for sure that the pressure is at 21 psi, it would indicate the OD cone cluth lining is totally worn out or the four main springs that load the cone cluth aginst the output bell are no longer doing their job.
Hope this makes sense.
Thanks for your help.
