2006 CDI transmission won't shift into any gear

4 posts in this topic

New to smart cars and this forum.  I recently bought a totalled off 2006 smart w450 that was side swiped from our provincial insurance provider.   The reason I bought the car was to take the motor and transmission out and put it in my 2007 joyner sand spider.   The car started and drove just fine when I brought it home.   I drove it around the farm and made sure the engine and tranny functioned properly with no faults.   I removed the engine/transmission and wiring harness to put into the dune buggy but before I went any further I hooked everything back up with it suspended on a stand.  The engine started right up no problems.  The dash, throttle and everything else works fine.   The issue I'm having is that when I select reverse or drive the display shows 0.  No gear selected.  Just like if you don't have the peddle depressed in the car.   I have the brake peddle switch hooked up and can hear the relay working in the fuse box but still shows the "0" when selecting reverse or drive.  Is the brake pedal the issue or is it something else?   Is there a way to fool it into thinking the brake pedal is depressed all the time so it will go into gear no matter what?  I won't be using the smart brake system as the buggy already has its own brake system already.   Any suggestions would help.  

 

On a side note when I hooked up the wiring harness to the engine and transmission when they were out of the car I only hooked up the connections I need for in the dune buggy.   The SRS system, seat wiring, climate control, brake/antilock brake system, door harnesses, and lights were not hook up when reenergized.  Not sure if this would have cause issues with the computers or not. 

 

Any info will be appreciated.  Thanks

i cant think of anything except for that brake pedal..at least youll get a thread bump

 

it would be nice if someone made a cheap affordable basic ecm for these things ..to use them as stationary engines or engine swaps

 

personally for dune buggy id have gone with something simpler and more horsepower like a newer snowmobile engine

I was going to use an arctic cat crossfire 1000 engine that I have that the diamond drive blew up on but when I saw this smart car in diesel I thought it would be kind of a second kind of cool to have a small buggy with a little turbo diesel in it.   I'm up for the challenge to get it working.   The buggy originally has a 26hp 650 with a 4 speed standard and goes pretty good.  If I chip the smart diesel to 60 hp with the 6 speed tranny it should be a decent match.   

 

Not sure how much weight the diesel will add to it yet.  

 

I'm more about the process of the build and taking the kids to the ice cream parlour at the lake then I am climbing up huge dunes.
