Velvet drive not engaging

My velvet drive was slipping, so I rebuilt it, on 1st test run engaged rev. Perfect. When shifting to forword it slipped slightly the engaged. Out on the water for slipped a little to engage once engaged worked fine. I figured it shouldn't slip at all. A friend added lucus stop slip transmission fix. Transmission then wouldn't shift out of gear once I got it out of gear, it wont go back into gear. So I checked to see if oil was being pumped and none was. I pulled shift control valve it seemed ok as far as I know . Can that lucus gum up the pump and cause it to stop pumping? I dont know what else it could be except pump problem

Tom,

With both hoses off pump the trans does not pump any oil out of trans.so I would say pressure is at or around 0, your right about the friend   , you think the lucus was too thick?

I kinda knew along that the lucus wouldn't turn to jello, I guess it was wishful thinking. The screen was also clean. I dont understand what could have gone wrong . To go from working, to stuck in gear, to wont engage.it was working fine once engaged, any ideas as to what I did wrong on 1st rebuild

I’m mot looking forword to pulling the trans again, if the shift control is not working how would I know? I pulled it out and it looked ok should i compress the spring pull retaining clip and make sure that cyclnder is moving freely, also is it possible to install it the wrong way or will it go in only one way

Originally after 1st rebuild it shifted into rev fine, for. Slipped a little then engaged. Then 2nd run after lucus was added wouldn't shift out of gear. Once forced out of gear it wouldn't go into for or rew. Would presure be present even though no oil is pumped out of trans if so I will try your gauge idea at those ports. I figured to oil flow no presure. Unless shift control valve is responsible for oil flow

Thats some great advice. Ill try that tomorrow. I’m not willing to start pulling the trans quiet yet

Sorry its been awhile I’ve been trying to remove those plugs to test the pressure, no way are they coming out. I had to cut open trans for 1st rebuild. Im going to pull tranny and tear it down. Hopefully I will find out what happened. If not I’ll be back on here. Thanks for your help

OK I finally gave up on trying to pull the plugs to check the pressure it just wasn’t happening so I decided to pull the tranny again this time instead of going through the starter hole in the bell housing I took the whole bell housing off and to my surprise the whole flex plate was not mounted to the fire with the screws were inside the bell housing but the flex plate itself was unattached I think I found the problem So I reinstall the tranny making sure the flex plate was hooked up which it was before and proceeded to start the motor well now the Cupler drive shaft and propeller spin however it seems to be stuck N forward and will not come out of gear It seems to have good pressure going to the transmission fluid cooler however it still won’t shift gears or come out of gear so I figured shift control valve I took that apart again decompress spring took out cylinder make sure sled really wasn’t stuck put it all back together and didn’t make any difference however I did notice when I have the shiftControl arm in Ford the breather hole will build pressure with my finger over it however with the shift control lever in neutral or reverse it doesn’t seem to be building any pressure I don’t know if that really is a factor or not I thought I’d throw it in there and see if anybody had any ideas

With the engine off are you able to turn the output coupling on the transmission?

With the engine off I cannot turn the Cupler

I hate to say but if you can’t turn the output coupler then the transmission is locked in gear and will need to be pulled back apart
