Coming home from the Roper last week I noticed what may be described as a "pulsating whine" when 3rd gear was engaged.
Vehicle towed OK & no problem accelerating up to 100kph with the overdrive off but the noise is a concern.
Has anyone else experienced this problem or have any suggestions?
Andy

No suggestions to help you Andy other than it sounds like a thrust bearing sound you would hear in a Landcruiser, the transmission in the F250 is renowned to be the weak link so if you have any thoughts that you have a problem i'd get it checked out by a specialist rather than be stuck somewhere. A friend bought his tranny / torque convertor complete from ATS transmissions in USA, wasn't cheap at $8500 but cheaper than sourcing an inferior product in Aust and it is a bullet proof unit.

Have a look at www.alcornautomotive.com.au, Melbourne based. Lots of knowledge about 250's.

Following on from Trackor 2's note - Does anyone have experience with Alcorn Automotive? The Agrovator Transmission Stage 11 on the web site looks pretty good.
It seems to me that if we have to pay for transmission work, which will involve pulling out, dismantling, finding fault & replacing + cost of spare(s) ending up with more of the same, a significant upgrade/replacement is the logical step.
The consistent theme on the F250 US web pages seems to be great engine but lousy transmission.

Hi Andy
Scott who sold you the wheels here.
Kicka toldme you were on the roper.
Would like to have meet up with you guys but after leaving heartbreak hotel about two hundred K's in the F truck had a terminal failure with the transmission.
After being towed back to Borroloola and then to Darwin the transmission was fixed by mick taylor automatics.
WE now have a twenty five litre oil capacity with a Hy Tec sump triple plate low stall torque converter. shift kit higher line pressures new plates ,pump etc etc.
PS we already had two transmission coolers and mick said two only tow in overdrive when over a hundred and the transmission is not working hard.
we are now back in sydney and the truck towed better than ever.
Best wishes Scott

G'day Scott
Thanks for the info. Couple of questions:
1. Did you have any prior warning of the failure, noise etc?
2. What did the work in Darwin cost? We are looking at $7,000 to $9,000 (depending on what unit) plus change over (labour).

Hi Andy,
It may be worth your while to contact Rocket Trucks Australia, speak to Don or Tim. Phone 03 9580 8155, www.rocketsportstrucks.com.au
They carry transmissions for the F-250 from BD USA, they have large sump pans along with specially beefed up internals. They also carry used transmissions.
Good luck.
Regards,
David

Thanks David
At Trackor 2's suggestion I spoke to Rod Alcorn & was impressed by his approach, we have decided to go with the Alcorn Automotive Agrovator Transmission Stage 11. At the same time with the transmission upgrade we will put in a chip.
Timing a bit loose at the moment as Jude has a touch of what appears to be sciatica but we hope before the end of August.

Just to finalise this posting.
We drove (2,000kms) to Melbourne & had Alcorn Automotive fit what is described as their "Agrovator Transmission Stage 11"
At the same time we had a chip fitted having removed the older one some time ago to keep the Transmission Temperature down.
Very happy with the result & found Rod Alcorn to be extraordinaly knowledgable about F250's.

Andy,
Can you tell us what chip they fitted and whether it has any control over the transmission. I have a Superchips and it quickens up the changes which I understand is better for heat issues but I do find it a bit jerky.
Also can you tell me why you went for Stage 2 and not stage 3?
Cheers,
Bill

I did not bother to ask the brand of the chip.
Without having the exhaust bored out & fitting an exhaust gas temperature probe the Stage 3 unit would have been an overkill, Rod recommended the Stage 2 unit. His advice is that the transmission temperature should never ever exceed 100 degrees C to protect the transmission & that using full power towing will create engine temperature problems without the mods above.
The chip has three settings, factory, towing (about 50hp above factory) and "go like the clappers". I opted for a conservative towing setting to protect the engine as well as the transmission. We have not yet towed with the chip, the gear changes in the "go like the clapper" mode are very smooth, it is a real pleasure to drive. Rod said that the changes will be a bit more "positive" when towing in towing mode for the reason you mention.
Without being in any way expert I understand that the chip settings do have an impact on the gear changes.
