My son's car is a 92 Diamante LS 3.0 V6 with Dual overhead cams.
It in mint condition EXCEPT the automatic transmission will only move
the car in reverse and 3rd gear. Fail Safe Mode?

The dealer says they can't diagnose anything until he buys a new
computer for it. (BIG bucks!) ie their computer can't read HIS
computer,

He has reset the ECM but now what? Isn't there a simple (and
cheaper) solution????

2nd gear is the "limp mode" not 3rd. In any event, you need to have the
transmission computer scanned to determine the cause. It could be something
as simple as a defective speed sensor or as drastic as the need to
completely rebuild the transmission.

Mitsubishi auto transmissions are crap. The cheapest solution for the car
is a match and a few gallons of petrol.

This is the cheapest solution also for Bhagatrolls. Unfortunately it is
illegal in most countries, but is really effective, and amusing too.

The original post is missing so I'll jump in here.....

I know someone who had a similar problem, albeit not a Mitsubishi. After
spending a fortune on computers and diagnostics he eventually discovered the
problem.....a faulty micro switch down in the shifter assembly. Start there,
it's the cheapest place to start.

I'd also suggest that if the car is under warranty and the dealer doesn't
have to equipment necessary to diagnose the fault then that's *his* problem,
and he needs to organise getting the car to someone that does.

No, but he *did* mention a "dealer", and it wasn't clear if he recently
bought it as a used car.
