A855 - 5 Speed

been a interesting read to say the least.

I just finished up (late March) a customer build 572 FHO Hemi / A855 5-speed / RMS Street Lynx / TTi 3" H pipe / DynoMax / 3" tail pipes to the valance. First test was between snows but never got into 4th or 5th gear. Due to weather, I made 10 or more runs with the car on a floor jack running thru the gears up to 120 mph plus to check for vibration / operation/ and to knock the powder coating off the surface of the rear Wilwoods discs. For what it was worth....stayed in gear A-OK.

I ran into the speedo clearance issue also....as I was finishing up the details, my bad for not catching it in mock up. Luckily, the customer had earlier choose to upgrade to all electronic gauges. My solution, and I see no reason why the a cable could not be routed under carpet to the gauges, was to make a approx 1-1/4" hole in the tunnel area right on top / above of the trans speedometer outlet to allow plugging in / out of the wiring harness. I used a rubber body plug with a small cut-out for the harness to fill the new round hole.

I know of two other 5 speeds, one that has been in for over 2 years with hundreds of miles on it....no popping out of 4th gear issues. And one being installed in HemiMarks small block 68 Dart.

I am / was among the confused..... thinking the whole A855 project was solely Jamies. I will add when I needed anything, information or product, Jamie delivered, on time.

Good luck, I hope your issues will get resolved.
