I have been troubleshooting my problem shifting (trouble getting powershift to engage), have done all the easy stuff and have moved on to the delay relief valve. When I pulled the cover plate there was no o-ring seal behind the plate, not surprisingly I found rust behind the plate and when I went to pull the DRV sleeve out I found it is rusted in place.
Has anyone run into this before, if so, how did you get it free? I have tried a few squirts of PB Blaster and mild tapping to try and break it free but don't want to break something while trying to fix it. I currently have a small folded up piece of shop towel soaked in PB Blaster being held in place by the cover plate.
One thing comes to mind, can I just use a jam nut against the sleeve and try to spin the sleeve in place to break it free? I can't see very clearly in my service manual if there is anything indexed in side there that spinning the sleeve would break or bend.
Any guidance on this would be much appreciated.
