Transmission Slipping?

Agree 100%

I guess my OCD would flare up and I would have to know my rebuild was good first.

When I did mine I assembled everything and had the same problem. My clutches were worn and needed replacing but my front pump was bad. So I had to remove the tranny and put a pump in. It worked very well after that.

Hey Kyle,

Did you have to use a shop press to do your rebuild? I have the ZF 450 D or ZF45c and it calls for a bunch of specialty tools to rebuild.

I did not use a press.

Most of the races and bearings are pressed on but mine were fine. No pits or signs of uneven wear.

I have not been inside of your style tranny before so my knowledge is probably not best on your style. I would have to get a shop manual and study it.

Wish I was more help

Transmission is done, garage is clean, waiting till thursday to drop it in. Between now and then I hope to have my strut aligned. A few pics:

First one is a little tool I made out of a PVC adapter, bushing, and dremel tool to hold the shaft in the middle of the log while I mess with the strut.

Next pics show how the strut sits with the shaft centered, strut loose, and my left hand lifting lightly on the back of the shaft. There is a gap along the starboard side of the strut and at the back as well.

I am thinking I will try a flat washer along the aft and starboard bolts, leaving the front three port side bolts flush against the hull, then tighten up and see how it sits before I bed it. If it is still not centered well I will use some thick glass mat with poly resin (dries quick and I am working against gravity). No big deal, but hope the washers work well enough

Hi Guys,

Hi Guys,

I have a 2000 X Star that slips/misses as soon as it goes above 3600rpm. I have added videos on youtube to show what the taco is doing.

Am i having the same problem?

At first i thought it may have been dirty fuel, fuel filter or fuel pump??

This video is from idle...

And this one is from 3200rpm up.

If the transmission was slipping would it gain revs not lose them ????

Yeah good call!

So fuel? (Pump or filter)

First, try and see if you can grind the bottom of the strut to get the alignment to the log closer. You dont need to be perfectly centered in the log- just fairly close. So long as youre not rubbing, youre fine- the log hose will take up the slight misalignment. Make sure you align the powertrain to where the shaft spins freely in the strut (not necessarily centered in the log).

Try and limit the number of washers you put under the base of the strut- and dont put too much thickened resin under there either, if you can help it.

Your boat has a taco???

I agree definitely doesn't act like a trans issue. I'd start by giving it a full service and see what happens
