F250 Auto Service

Good Advice from Brian,

But Boggers, unless you HATE your transmission, when towing drain the system and the cooler every 30,000 kms, drop the pan, and change the filter pickup in the pan... Or have it done. Personally I think Brian is VERY lucky not to have had the transmission fail in running as long as he did without changing the oil... VERY LUCKY..!

You can stretch that if you run synthetic, and you SHOULD run synthetic unless you have a transmission temperature guage or additional tranny cooler... But I would dump mine at 30,000, cooler drain and all even if you run synthetic... And here is why:

Abuse it, and you can go through a tranny.. Three Bushtracker Owners have, and maybe 7-9 from memory in the horse Industry, just by working them too hard in the heat with regular oil and poor service... Mind you that is out of probably 300 Fords.. However I did with my own, on my old F-350 about 5 years ago, towing a 29' gooseneck horsefloat off-road in very hard going.

That is why I have done a full engineering study on the E4OD and the 4R100 transmissions you have in your Fords.... To the extreme of supervising rebuilds of two, with Aftermarket Tow Package clutches and all...

They need to run on something like Castrol Transmax Z synthetic oil that can take much higher temperatures... It is bad enough not many shops have the capability to flush out the Torque Converter, so you don't get a full change and flush anyways, that is ANOTHER reason to keep it down to 30,000 or so kms between changes.

There are a couple of TIPs on this is any one is an enthusiast like me, or wants to do the best by their horse... LR...

Hi

To add to this discussion, Big Red has been as the doctor for two weeks! Something to do with oil pressure and the injectors - something they can't find out about without constant consultation with Melbourne and the USA.

Runs fine on the flats; no power on the hills and stalls.

The "biggy" they have done so far is to change the injector "o" rings which were stuffed and that helped about 50%.

Sure glad I purchased the extended warranty.

Will keep everyone posted when they finally find out what is wrong.

Steve,
Do your recommendations on auto transmissions also apply to Tojo?
I have 90,000km on my 2003 LC100TD, 58,000km has been pulling our 20'BT. Have had all recommended services & have had transmission fluid changed as per book.

Look forward to tour advice.

Got the F250 back today after the repairs. The circlip that retains the overdrive Piston Return Spring in place became detatched and allowed the Overdrive cylinder to rub inside the torque converter. Everything else inside the transmission is still in very good condition.

While doing the repair they changed the single Retaining Ring to Spring Retaining Ring, and upgraded the clutch to a heavy duty towing clutch.

Apparently the transmissions in the earlier model F250's brought into Australia were not really suited to heavy duty towing.

Cost $1600
