Second Gen ECU / TCU Failure (An Overview)

[cws]

Tried to repair the original damaged TCU today, replacing the main 3 x blue capacitors, and plugged it in to try it out.
Still clunks into reverse... and not sure if it was getting out of 2nd gear into Drive when in Drive mode.... but at least it works as a temp backup unit.

Also pulled out the spare TCU that was implanted in the originals place, found its 50V 47UF cap was also leaking, so replaced it then re-installed. Didn't change the others as they seemed to be OK.
Seems to work OK on a test run... time will tell. Wasn't too hard to remove and resolder the capacitors.... although the not the neatest soldering job... guess I got away with it for now.
Thanks again for all the guidance.

Hi TPWagon,
I noticed your post where you comment on a "cut of power' fault. I had a similar problem with my TP. Your description of the problem precisely describes exactly what I experienced. In my case, the problem turned out to be the module in the distributor.
Hope this helps.

I'm also experiencing shifting problems on my magna TR 2.6 I have this car since 2006. I just pulled the TCU and this is how it is. Someone has toyed with it even before I got the car. The capacitor has been replaced with 47uF 63v I can't figure out the manufacturer. I doesn't seem leaking but I've read somewhre on this thread that they can dry up without even leaking. Im no eleco buff but I'm going to replace this and see if it works before I go to the wreckers. by the way it was soldered previously I think I can manage myself.
