My auto transmission was randomly stuck on third, a classic TCU failure
symptom! I decided to open up the TCU and play with it before
purchasing a replacement unit. I as inspect the board, I found two
adjacent transistor (220uF) and resitor (10K Ohm) burned. Went to Radio
Shack, purchased the two items for a grand total of $2.29, replaced,
and the problem is fixed! Hope this post helps someone with the same
TCU problem.

I have a PDF and a link where a guy explains how to do that fix . .
apparently it's very common for the caps to eventually fail, which takes
out the other components. google.com is a great tool for such stuff.

don't confuse people, the value you give for a transistor is in
micro-farads, which is a capacitace measurement. some people only
read and have no understanding of what they are doing.
I've re-built several of these for people. it is cheap and easy

Yes, you are correct. It was a capacitor, not transistor. Thank you for
catching the mistake.

CURLY If you are still out there. I used to have this site linked (The one
where the guy goes into detail on how to fix the TCU with radio shack parts)..
. do you still have or does anyone have a link to that site?

I'd really like to get it - print it and put it in my glove box. My TCU went
out and I was fortunate and found an inexpensive one on eBay but now it has
gone out! I'd like to take one of these and properly fix it with the Radio
Shack Parts that the guy mentioned in his repair article.

Thanks and please e-mail me at MotoMikeeeP@yahoo.com if you can find that PDF
file or the URL to the guy site.

Mike
