Thread: 93 T-Bird Tranny problem

Denny,

I spoke with the guys at the drivetrain place.. Turns out there is a circuit board you install in the tranny oil pan that goes between the power train computer and the torque converter lock up control valve. It intercepts the screwy modulated computer signal and stops the SHUDDER.

I ordered one.. I'll keep you posted.

Kinda makes you walk away scratching your head,,,wandering why they didn't build it proper in the first place,,,i mean,,,they do test them before releasing to the public,,,so they must know.

ahh Thunder,

I Suspect the auto tranny is by far the most complex item in any vehicle. Mix this with trying to make it cheap and you probably end up with shudder problems that are in a hard to troubleshoot package. I mean come on, hydraulic/spring based logic. Gads!

Then the service system would rather pull and replace because of the horrendous labor and the cut on the high priced material.

Now if I was designing a tranny.... It would have NO logic in it at all. It would be entirely computer controlled. I don't understand why this hasn't been done yet! Then it just becomes electric valves that run each of the three to five transmission states. No springs!! No orifices! No shift plates. No shift bodies.

I had a washing machine that blew its nightmare timer control. I bought a new control $70. It failed in 5 months. It had probably 20 different bent metal spring contacts. I tore that out isolated every control mechanism, about 6. I hooked them to a junk
PC thru isolation. I wrote a few basic programs for the different types of loads, diapers, towels, etc. That worked for years! Until the transmission dropped out. The same would work on these trannys.
