    Towing empty box 7 x 4 trailer. Sat on 90-95 kph.After about 200 k it revved to about 3000 and speed dropped. Slowed down and it seemed ok. It happened another three or four times over the next 50 ks. Checked the transmission fluid and added about 750 cc. There are no obvious leaks under teh car. Nothing sprayed back on the underside at all. Went for two drives of about 6k. Headed back home with about 200 kg in the trailer. After about 50 k it did it again. checked the fluid and it was OK. Seemed to be bubbly. 10 k down the road smoke started pouring out. The dipstick was a bit wonky and maybe I didn't ensure that it was properly locked in and it spat out and transmission fluid all over the engine bay and exhaust. RACQ got me towed home (140k) as the guys said it was a tranny problem and would take more than 48 hours to fix. The car has only done about 160,000k , mostly in Townscville city and suburbs. Not a real lot of highway driving prior to my getting it and was running OK until this. Would the low fluid have damaged the transmission or is it possible that the fluid had sprayed out quicker and the loss of fluid caused the issue. If it was manual I would describe it as a slipping clutch, but it was not consistent as a slippery clutch is. Any ideas. I have a local mechanic who has a 2nd hand box. Haven't spoken to an auto tranny specialist as yet as it only happened this arvo. Thanks in advance

    I'd get an opinion from a transmission specialist. I had very similar problems and people told me the issue was the trans. Some said it was solenoids but it wasn't. It turned out to be the TPS.

    Mine did something a little similar when hot and climbing the 10km Dorrigo mountain. In my case, in 3rd, the TCC was repeatedly locking and unlocking. I've since replaced half the fluid as the old stuff was brown and bubbly. Seems to have reduced the incidence, might have solved it but I've not had a similar long climb since.

    Drain and drop the pan for a look. Might just be able to get away with a new filter and fluid change. Or might need a flush to get all oil out from the converter as well of it is dark.
    When was it last serviced?
    Do you have an external trans cooler fitted ?

    Looks like tranny was serviced at 4 years (27,00k) , but that was in 2001! and book says do it again at 8 years, if kilometres not done. Only cooler is the standard fitment. may just try a service first and see what happens.

    Get the transmission serviced and an external transmission cooler installed. Only tow in auto third gear (no overdrive). Sounds like your transmission is overheating.

    Or tow in power mode, basically it will stay in 3rd when ever it's under load and it'll bump up the line pressure a bit to and as the others have said, get it serviced pronto and fit the largest external cooler you can find and hope no permanent damage is done.

    Don't use Holden's service schedules they are way too far apart.

    I can get a VS wagon (haven't looked at VIN for year) with a recon gearbox from a mate for $800. They spent $3000 in the box. Are the wagons and sedans the same gearbox. VIN code mentions engine type but not gearbox.

    Jee that's a lot spent on a VS transmission. I had a full rebuild on an AW4, including reconditioning the torque converter for $1800. Having a donor car is a good idea but I wouldn't assume your trans is buggard. It needs a service first and then see what happens.

    I changed the TPS and the problem went away. Don't ask me why the TPS affected my trans and made it felt like it was slipping and had no drive because I have NFI on the electronics that regulate how a modern trans operates. I just know that replacing the part fixed my issue. People on here was telling me it was solenoids. But I checked with my trans tech and he said replace the TPS and see what happens. Mine revved out 2 or 3 times on different occasions like the Op's, like it was slipping did it around 90 -100kph. It wouldn't move when it revved I had to pull over and restart the car to get it going.

    But given the OP has shed light on how long it has been since it was serviced then like everyone has said it needs a service before anything else.

    Do you have VR or VS?
    My VR series 2 did not have the external trans cooler when I got it, but was recommended to when I had the towbar installed and told to leave it in 3 when towing. Just went to the wreckers and picked one up for under $20 with brackets and hoses.
    All the VS I have seen have had the external cooler already fitted even though they did not always have a towbar.

    I've not had a factory fitted vs one without the towing or country pack.

    Transmission line pressure is determined by throttle position Vs road speed.

    Interesting about driving it in power mode. I have always done that for a long time. I heard years ago it's better on the trans to drive it in power mode, towing or not. Hence I never turn it off. I don't have a ext cooler on mine yet but my trans tech is fitting one in a few months time when he services the trans.

    After the VS, Holden increased the size of the Auto Transmission fluid capacity. You see references to DEEP pan.
    That was probably cheaper (for Holden) than fitting transmission fluid coolers to all Commodores.
    The standard radiator spec also had oil cooler tanks in both ends of the radiator by the time the VT2 and VX came out.
    I know transmission coolers are a good thing, my 1974 Torana (sad) had a small leak in the oil cooler. The old man fixed it, by bypassing the oil cooler and forgetting about it. Obviously it was all my fault when I drove the car on the day that the auto transmission failed. $1500 estimate from the mechanic meant the end of that car.
