Transmission Trouble in 04/01 AUII - help!

[XA Coupsta]

Hi Guys,

My 'other' car (apart from the coupe) is the family AUII Falcon - 04/01 - bout 95k on the clock.

Just came over to my inlaws house for some lunch and the transmission is playing up bad. First time its happened.

This is what i've got - can anyone help?

1. It all started after - sitting on 60kmh - car climbs in revs for a short minute and im like "What the?...". Didnt feel the gears change around or anything - but it must have gone back a couple of cogs?
2. Immediately after I lose the speedo AND odometer.
3. Car doesnt seem to find 4th gear? I can feel it go through all three gears but not the final - regardless of speed.
4. Car is very doughy off the start. Revs dont match road speed. Even if I floor it car doesnt jump at all.
5. However if I manually select 1st - then hit it - it will break traction


So - my thoughts are either ECU related? (are the speedos cable driven in these things or electronic?)

OR

Torque converter. Again Im not sure if these are electronically controlled? But it isnt engaging properly with my test between putting it in D and accelerating hard (and it goes nowhere) or selecting 1st manually and accelerating hard and its fine.

All help appreciated! It will be going in to the mechanics tomorrow but I like to have my homework done before doing so.

Cheers,
Coupsta
