Upon completion of a flawless Trilogy install by the shop forman where I work, we let the Marauder sit and idle for about 30 minutes or so while we checked for fluid leaks, squeaks and other assorted glitches. None. Absolutely none. She purred like a tomcat in a cream jar. Idles same as stock, punch it and up comes the boost and the whine. Ok, lets drive. We set out in city traffic and are stuck at 20 MPH. This ain't gonna work. We know it's fine at slow speeds but just how much grunt does it have? We find a empty side street and pull off, come to a stop, let it idle for a minute or so and from a dead stop punch it to the floor. Perfect. It comes off the line fishtailing and smoking both Nittos, they bite and we're gone. Rather than let her gain to much speed I quickly (it seemed quickly anyway) backed off and came back down to a very safe street-able speed. We cruised back to the shop grinning ear to ear.
One hour later we head for home when a funny thing happens, no third gear. Now what? Well it was fine before the install so it's got to be some thing that happened in that process, right?
Nope. Short version of a very long story. After talking to some of the best brains on both sites a transmission tear down found that the INTERNAL snap ring on the direct clutch pack had popped out of its grove and allowed all the clutches to escape. Hence, no third gear. We all know about the external snap ring on the mechanical diode that's problematic but this is the first time I've heard of this one failing.
I hereby claim the worlds record for the shortest lived transmission after a Trilogy install.
I have talked to the pros and read numerous posts about how you can flog these transmissions unmercifully and they still hold up. Not mine. Broke the first time it was pressed. Kinda like a virgin getting pregnant on her first experience.
Any way, all's well that ends well. I've now got an "enhanced" transmission bolted in and it shifts nice and firm and seems plenty sturdy.:beer:
Here is a photo of the direct clutch drum and the offending snap ring.
