Can't see oil cooler pipes on new box.
Selector shaft was done for different applications,

Pic 4, Reply 43. RH side of box as standard.

I am just looking for a cap to cover the speedo pickup, and its ready to go on. Rear sump to be changed when fitted.

Digressing slightly, box is made in France, yet bell housing bolts are imperial head size!

sacre bleu!

4l30-E is a US designed box (its been developed over tens of years!) made in Strasbourg.....hence imperial fastenings as the yanks are further behind than us

I noticed that.

Almost ready to go on, just awaiting a different sump. However, having removed the transit bar and torque converter from the new box prior to removing the bell housing (which is to be swapped with the one coming off the TD), I am unable to turn the gearbox by the propshaft drive plate, even when applying reasonable force. As the transit bar locked the box via the torque converter, I cannot imagine it will be locked elsewhere. It has been sitting in a shed for at least 6 years, but is full of clean ATF, and I am at a loss as to why it will not turn.

Any ideas, other than apply more force assuming it is just stuck?

A guess, but could it be I 'park'?

[Shackeng]

Of course! Slaps head in disgust. I'll report back.

[Shackeng]

It was exactly that. Believe it or not I used to have a brain, but it seems to have gone AWOL lately.
Thanks Steve.

No worries, my problem is I only seem able to see these things when it's not me in the situation!

Bugger, I thought it was all going too well. I have belatedly examined the two electrical plug connections on the LH side of the box and spotted that they are in reversed positions, indicating that they affect solenoids in different parts of the box, and also the large round connector is a female receptor on the new box, but male on the old one.   Also even if I swapped the round plug, I would have no idea which wire went to which connection in the plug, although I suppose a Haynes Senator wiring diagram might help IF the colour codes were the same. All in all I think it is a very difficult proposition, which is a great shame to have to lose this brand new box.

                                                                         New Box Connections


                                                               Old (AR25) Box Connections

I think this is probably a deal breaker,  as even if I swapped the plugs to connect to the new one, it seems unlikely that it will operate correctly with my ECU. Of course I have the Senator ECU with it, but to integrate that in the Omega is a job too far for me.
Ah well, such is life. Back to plan A and repair the old box with a new thrust washer.

With the sump off, swapping the internal wiring loom and connector should be pretty straight forward.

Was thinking the very same

[Shackeng]

But do they do the same things inside the box? Just spoke with an autobox specialist in Leicester recommended by BigTime. He advised that the ECU will quite likely read fault codes if everything is not identical. The reverse gear is  a different ratio by only a small margin, but he says this could well put it into limp mode.?

I guess this is worth a try, I was just hoping only to have to do the box swap once, and if this didn't work it will be twice, and at my age will probably kill me.!
