Ishift - Whine sound

Sorry its taken a while to answer the posts, I really do appreciate the input

Got the oil off amazon , 1 gallon was 38.60 with free prime delivery. they have 4 gallons for 129.00

The noise is from the transmission, happens no matter the speed or load in any gear up to 6th. Rode on the back to make sure it wasnt something in th edrive train, suspension etc. It sounds like a turbo when it whines

Havent had time to mess with it since last post, hope to crawl under this weekend and add some fluid but i dont think its going to change the whine sound.

So if this was your truck, would you have the transmission removed and opened up to find the issue? Or drive it as is and roll the dice?

 

Thank you for the reply.

I added about a half gallon of oil to the transmission, that was fun trying to get it in the side hole with no room above to tilt a bottle into a funnel , ended up putting the oil in a squirt bottle and shooting it in until it started to run back out, which put it at the full indicator in the view glass. Took it for a 120 mile test drive, whine sound still there, really no difference that I could tell.

When I purchased the truck i was able to get a 3rd party warranty, it does cover the transmission all moving parts, bearings, bushings, shafts etc. there is a deductible, a cap at 12,000 dollars lifetime, and it doesnt cover the cost of diagnostics, shop supplies, etc.. I also see Volvo has a remanufacture program with 3 different tiers for transmissions, have no idea the costs of those tiers or the labor $ to replace one.

There is a Nacarato and also a Nextran shops fairly close by, was thinking about speaking to their respective service managers about the 2 options above, weigh the cost vs risk and see where that gets me.

This tractor will be hauling our full time home so it needs to be reliable as it can be, for a used truck anyways. I also want to get some changes to the programing, top speed is now capped at 70MPH which can make it difficult to pass at times . Also the adaptive cruise control cant be changed from the far setting, so would like that changed as well.

Again I thank all who have read and replied.
