A '00 CVPI would use the XW7P(-7000-)BA and -CA versions from the factory.

XW7P(-7000-)AA and DA are civilian /retail model transmissions. These do not have the extended tail shaft housing and extended output shaft like the CVPI transmission.
The extended tailshaft housing can be swapped over from your existing transmission (install new bushing. Or just install complete new tailshaft w. bushing) to use the retail model trans. Your CVPI driveshaft has a small vent hole in the center of the yoke. Plug this hole if you use one of the short output shaft/retail transmissions with the extended tailshaft and your stock driveshaft.


Additionally, the retail model transmissions will have an 8 tooth VSS drive on output shaft (vs 7 tooth 99-02 CVPI). A new speedo gear will be required to keep the speedometer accurate


FYI, MANY different years/specs could be used by swapping around basic parts.

well this transmission in this is an yw7p-aa transmission and it is a crownvic police interceptor. i bought the veh from town and country ploce department, and it is the p71 vin etc. i believe its the "high performance package" if im not mistaken. but what all would it entail to swap once of these other transmissions in?

There's no such thing.

Also, this page has a ton of info on different transmission models and part interchangeability.

Nope. That's something different. HPP stand for "Handling and performance package"
It's a civilian model with classy features. Not sure why it has a different transmission though.

You have to remember, these are used vehicles that were beat to hell and part of large fleets. All sorts of stuff gets swapped between models and years because most of it is interchangeable or only slightly different.

It is extremely common for a used CVPI to have the 'wrong' transmission installed, so don't get hung up on it.

Depends on where it is leaking from. If from the CENTER of the driveshaft YOKE, then you likely have a retail model transmission / short output shaft.

You mentioned you have a YW7P(-7000-)AA trans installed right now. This is a retail/civvy spec trans (for HPP cars) and has the short output shaft. The tailshaft housing may or may not have been swapped. About how much space is between the base of the yoke flange and the tailshaft bushing?
The CVPI long/vented yoke needs to be plugged when used with a short output shaft trans to keep it from leaking, as I mentioned earlier;

The XW7P-BA and -CA versions would be a direct swap.
The XW7P-DA version you listed could be used by swapping the output shaft and plugging the yoke as mentioned earlier. You will also need a different plastic speedo gear with this trans, a 23 tooth (assuming you still have stock 3.55 RAR)

'00 HPP models received a transmission with 7 tooth VSS drive output shaft instead of the normal 8 (but with normal short output shaft and tailshaft housing), as the HPP went with a 3.55 RAR for '00 model year. The VSS/speedo driven gear required for 3.55s with 8tooth drive self destructs (very high tooth count (23)) by like 10k miles, which obviously won't work for an OEM application. The 7 tooth drive is required so a lower tooth count gear (20) can be used for increased longevity.

How do you plug the hole?

Most have just used RTV (clean yoke very well with brake cleaner before applying). A few actually tapped the hole and installed a plug but this requires removing the U-joint first, of course.

Many just run it as-is, and either never noticed/don't realize it leaking or have and don't know why it is.


It is more prevalent on those with the forced lube mod.

This picture, courtesy Steve83, shows the vent hole position and typical underbody grime/oil on the tunnel resulting from the leak;

Thanks, I noticed mine was leaking out after I changed my transmission fluid. I suppose I'll climb under there and silicon it shut.

so they are interchangable without any swapping of any parts except possibly a yolk?
