904 transmission shifting adjustments

Did the trans guy just put new clutches and seals in trans or did he install the manual v/b kit, you need to get more info from him. It looks like you can do various things on your car you mite want to spend less then 100.00 an buy some tools and read some information on transmissions, they are very simple
I have used 2 manual v/b in the past t/f forward pattern and rev pattern both had full line pressure, there are ways to make it manual v/b and keep the throttle pressure stock (needing linkage from carb). It sounds like test time like kern dog said the linkage arm needs to be all the way back and will give full line pressure, take for a road test and report back.
