Auto TRANS won't drive

[Sprock]

Yeah me either Mark , when I changed the auto fluid last weekend I pulled the sump / pan thingy off for a look & you can't see bugger all , there's a big plate there with lots of wires and plugs and not much else, I guess the real workings are up inside it. I didn't know what to expect but I thought I'd see more than that ha ha

Yeah I'll be on the phone in the morning Jay see 😩

You can't get an air lock in the auto fluid can you?

If any of the clutch packs were worn to the point of allowing excessive piston travel, the slip in your shift changes would have been quite noticeable and there would have been a lot of debris in the pan and on the magnet - unless you recently purchased it and the fluid change was done beforehand.

As suggested, a pressure test would be a good idea but you'll find most shops will want to overhaul it.
If you're reasonably mechanically capable, doing a rebuild yourself is possible with the factory manual.

Could really be anything, worn clutch packs, broken wire, damaged seal.... when my auto died in the GQ it was pretty much everything

Agree with the sloppy shifts when the clutches are worn, but I guess it's something that may not be so noticeable to a lot of people as it has slowly worn over time.

yeah that's what I was faced with mate ! I've had 18 Spd truck gearboxes apart before & can understand ( to a point ) how they work but there wasn't much to see in here

yeah I'm not confident it'll be a simple fix

I took it up the snow the weekend before & flogged the arse off it & it was fine , it was totally outa the blue . Got me fucked . I'll ring wholesale automatic transmissions on Monday when they open - they're supposed to be the gurus .

If your handy on the tools Adam, as John said a rebuild is possible, you just need the time, tools and space..... none of which I really had. Do you know what model gearbox is in yours?

Well mate I have the time now because I drive a log truck and we just finished last week due to the snow but its six of one - half a dozen of the other, I could take a week to rebuild it myself or I could go and do other work for that week and pay someone to do it , hopefully i'll know more Monday morning when I talk to the auto specialists and get some direction, rebuild cost or change over box etc to see what's better , it's like with truck diffs , you can take two days and rebuild it yourself but you lose two days of work so change over is better in the Long run, might be the same option here. Still up in the air as it wasn't part of my plan for this week ha ha
