I can hear it engage but I don't see my front tire pulling

Making a 'whining' noise as revs move up and down,

while driving, all of a sudden all of the interior and exterior lights and gauges started to flicker and the door locks started to lock and unlock automatically.

They dealership calls it transmission cooler lines that were rubbing together causing fluid to run low.

which caused the transmission to go bad. There were no indicators to tell me something was going wrong. The only thing was a burning smell which caused the truck to drive slower. I pulled over to the side of the road and called a tow truck. All this happened July 11th of 2015.

when car is a idle the noise is very soft but increases with rpm.
took to a local shop and said it is coming from the timing chain area nee to know if the tensioner starts to go bad will this cause the noise or is the chain or what else it could be.


I have a 79 international scout that I did an LS swap in. The engine is a 5.3 out of a 2008 Tahoe. The trans is a 4L60 out of a 2007 Tahoe (supposedly). The transfer case is a NP241c. Today is febuary 7. Since Christmas the tranny has failed 4 times. The tranny shop said the trans oil pump is being destroyed each time. They have tried shimming the torque converter, changing out the bell housing and some other stuff. I just had the scout dyno tuned today. The Scout is running good for now but, on the way home code P0741 came up. I did some research and it says that it could be the torque converter locking up, bad valve control body or a bad lock up sensor. Can anyone please help me with this? I did this swap so I can have a more reliable vehicle. I cant even enjoy my Scout because I'm afraid of it breaking down on me. I live in el mirage, az. If you can recommend a good shop that can fix the issue, that would be a great help also.

from my rear end differential. Can I just add differential fluid

Gauge not working
