Title: Trimatic overdrive unit
Post by: BusyKiwi on April 09, 2010, 06:51:18 PM: I've been hunting for an overdrive unit like a couple of the members have on their vans. Some trans people know what I am talking about others don't.
It appears the name of the thing is a lazycock, is a universal unit that will fit several things, have heard they have been fitted to trimatics, C4's and others.

Now to find one ....

hopefully this little bit of info will be helpful to someone. When i do find one i'm going to strip it down and will take some pictures.

The downside to these units is they don't have a powerlock - will freewheel in gear

Going to be mucking around with that soon because if it's true should keep the revs nice and low on the free way
