Help they say my car is non reparible

[elaina]

2004 VZ Commodore 5speed automatic with active select shift paddles

I drove for (4hours)
The car started saying check power train and I was loosing gears
When I got to Destination I still had 1st 2nd and reverse

So we got a transmission service kit and drained the transmission and put the new kit in then had no gears but realised we left a little plastic collar/spacer out we drained it again brought more new oil and put the collar in and then I had 1st, 2nd, 3rd, and sometimes 4th, and reverse no overdrive but couldn't drive over 80ks

So we brought a new pressure solenoid and we drained it and the solenoid was the wrong one so we then just brought a whole new valve body

today we put the new valve body in and another brand new transmission filter and another lot of new transmission oil and now again we have NO Gears
at all

Seriously either take it to a transmission specialist, or just bite the bullet and put a second hand unit in.

Probably spent close to what a reco or good second hand unit would cost just blindly throwing parts and oil at it.

It's going to an uphill climb to have it recoed and finding a good SH unit will be near impossible. This is why you have been told what you have. You are looking at a $6k or so repair bill.

Correct. The 5L40e is a dog gearbox. If I had my time again, it would be on a manual conversion. Much simpler long term maintenance.

The 6L80e conversion would also lift the car to a new level of driving enjoyment for similar money.

Has anyone figured how to do the 6L50 conversion on a 5l40e yet?

Been there, junked that with my previous VE SV6. The 5L40E transmission is rare as rocking horse **** and expensive to rebuild, and you get no guarantee with a rebuild that you won’t be back to square one within a couple of years as they are difficult to rebuild by all accounts.

Either convert it to a manual transmission or junk the car and get another one.
