I managed to track down a local SKF agent who can supply me with the right sleeve (CR 99193 or its Gold version CR 99833) that will cost me far less than a new coupler, so I'm going to sleeve it and see how it goes.
After more than three months, the rebuild parts I ordered from Basic Power Industries eventually arrived last week. So I got back into the build process this weekend, and only paid a close look at the belleville spring for the first time today after cleaning it up - pictures below. It looks pretty worn to me - specifically there's a very noticeable groove worn into it where it contacts the clutch spring bearing ring . Due for replacement I guess? Or still re-usable?    |

And here is a picture of my input shaft, which also looks like the surface on which the seal runs is not in great shape (apologies about the poor lighting, but this is the best resolution picture of the shaft I could get). Plan is to sleeve this as well. SKF CR 99138 (or 99819 for the Gold version) seems to be the right one.

I had the same problem years ago on my Mustang. One of those sleeves fixed it right up. Dont remember the size though.

Basic Power Industries very helpfully provides the dimensions of the sleeves on their website.

Can someone perhaps shed some light for me on the following? This service manual says on page 37 to use twelve reverse clutch pressure plate springs, but this service manual says on page 22 (page 30 of the PDF) to use only eleven. Which service manual is right? If eleven is the right number, why on earth would the pressure plate be machined with twelve spring holes, and not only eleven?
My transmission had twelve springs installed, and the spring kit comes with 12 springs, which suggests twelve is the magic number, but I want to be sure to get it right.

Transmission coolers should be considered a wear item. When the tranny needs to be rebuilt, it is time to get a new cooler. They are not that expensive, yet are pretty critical. If they start leaking or are clogged up, you likely will not know about it until the newly rebuilt tranny is toasted again. Then you will wonder why you tried to save a few bucks in that area.
Just my opinion of course.

New cooler is lying on the shelf waiting to be installed. I didn't order new cooler lines though - just flushed the old ones out. My thinking is they're easy enough to replace if they should spring a leak at some point in the future, so until that time, I'll run with the old ones. Things which can cause trouble/leaks and are difficult to replace without pulling the trans (seals, sealing surfaces) I'm not taking chances with.

I still don't have clarity on this. Anyone with some insight here? Ken suggested that the springs have eleven coils, and hence the 11/12 confusion, but that is not the case: there is definitely a conflict between the two service manuals about the number of springs to use.

Ken deleted that comment about 5 minutes after it was posted,after he looked at a spring and you changed your reference page 12 springs came out, put 12 back in |

Considering that if you buy a new transmission or in many cases with a rebuilt unit also, the warranty is void if you don't replace the cooler, you can call it whatever word you want to use I suppose. |

11 reverse springs are used not 12 and your cooler is either good or bad but it doesn’t hurt to replace it during a rebuild along with your damper plate

You are now filtering the transmission fluid?

Early models had 12 holes newer models have 11 holes not sure of the reason but when I rebuild them they all get 11 springs

And Wilhelm was comparing an early manual with a newer manual.
There's your difference Wilhelm

Heh, Ratty rocks, an island of sensibility
Yes, a local hose shop made a third hose for me, set me up with the hose connection to npt fittings to run a remote filter. it goes into the filter hot for best flow, then to the cooler. |

Great info, thanks Joe. But now I'll forever be wondering why Borg Warner changed from 12 to 11 springs. And why using 11 springs on an older transmission with 12 spring holes is better than using 12 springs. I never seem to get to the bottom of the rabbit hole with these things! |

Just me, but just cause Joe uses 11 and yours was built with 12...........I 'd probably put in 12 and not worry about it.

Putting 12 in isn’t going to hurt anything so instead of wondering just put 12 in and don’t worry about it |

Came across quite a nice disassembly video from Hale Marine here: video.
Question: at around the 7:25 mark, the presenter mentions that the bushings inside the pinion carrier assembly/output shaft hadn't spun. How can one tell if they have spun or not? By confirming that the bushing holes line up with the shaft holes? Or is there something else?
