borg warner transmission

I have a 85 2001 500 hrs, recently the trans slipped (less than a second) while pulling up a barefooter, 30 minutes later it did it again, we ran another 2 hours with no problems The local mechanic I spoke with wants to rebuild. Should I run it till it stops or have it rebuilt now. Also, how much fluid does it hold?

if you slipped it, a good indication is dragging in nuetral, the true test for drag is holding the prop shaft by hand at 1100 rpm, you should be able to hold it(safety note: don't wear a scarf while doing this test. if you cant hold it you have some warpage in the plates. you can put a gauge in the trans and check pressures, figure out the problem first. then decide if you need it rebuilt. start with the oil level first

Check the fluid level and quality -- burt, stinky, looks like peto-bismol? Top off the fluid or replace if needed.
Here's my opinion on the rebuild...
A rebuild is in your future. Even if the fluid was low and that was causing the slipping, some damage was done and you'll need to rebuild at some point.
If the tranny isn't slipping too badly, I'd continue using it through the end of boating season. (I live in Texas and we ski up to Thanksgiving sometimes.) I don't think anything else will break and need replacing if you don't rebuild it right away. That's my thinking on it. Maybe some others have a different opinion?

Here's a question for you eric regarding a 1:1 borg warner

I figure it was due to my buddy using thewrong snap rings in the wrong place from what I've read, their more of a sim than retainers, but mine does creap forward some times when in nuetral, I can grap the prop shaft by hand and hold it and bring it up to 1100 rpm and still hold it do ned to worry about it?

eric you the Man,have mine tore down now awaiting a box of goodies from you. looks like a good weekend project. the PCM manual is really a treasure chest of info,from rebuilding trannies to adjusting timing and idle speed.lottsa info for a little money.Eric how did the road trip go,did all the kids and dad survive????????? i remember those days,that is why they don't give kids to old people,and if i would have known grandkids were this much fun i would have skipped the birthing process of my three..............boat dr

boat doc, you better ad a 0 onto that 3 lol

no problem Jim,i think I was poking at the beehive a little bit in the beginning, I guess i didnt understand what a close knit group you guys were, eric
