Transmission Fluid Pump

Here's an example of a Velvet Drive 5000 parts listing showing the diagram. Part # 220 is the filter/screen.

Here is the "Liberty" trans (might be the same as a 5000):

Thanks km1125. I’ve got a request in to an online parts supplier for a parts diagram but from yours, I think I can see a similarity with mine. Is there any issue with removing and reinstalling the spring and piston that are under the same cover as the filter? And can I just clean the filter?

Today I ran the boat briefly to check out performance after replacing plugs, wires, rotors, distributor caps, oil, fuel and gas filters. I ran in forward at WOT for about 5 minutes with no horns or other anomalies. On return, with engines idling in neutral, I checked some temps. The port tranny was about 20 deg. F warmer than the starboard and both were cooling down pretty quickly. Also, I found a 10 deg. F drop on both sides across the tranny coolers. I have a mechanic coming to read codes on Friday and I hope this is just a bad sensor as Viper suggested.

That still doesn’t explain why I can’t get an accurate fluid level reading on the port side by following the book. When the book says to stop the engine and “quickly” check the fluid level, what is “quickly”? I can get there within about 20 seconds on my bum knee when I do it myself. Do I need to get some help so I can read it quicker?

The early Velvet Drive 5000 series had a pump problem which would act just as you describe. It was some sort of casting problem where the pump mounted. It was more prevalent on the port side for some reason. They tried a different gasket (#2001-045-005), then a different pump/valve assembly (#2001-736-003) and then redesigned the whole thing and called it the Liberty instead of the 5000 because of the bad rep. Most of these were repaired or replaced a long time ago but there are a few low hour ones floating around. I'm not saying this is definitely your problem, but it was big thing around your model year so it is worth investigating.
