Valvoline changed transmission fluid and over tightened the plug when finished and cracked the transfer case. Is this the right fix? Valvoline Instant Oil Change suggested I have them replace the transmission fluid in my 2005 Mercury Mountaineer and I agreed. I was then getting a new tie rod put on and the mechanic told me there was a leak from transmission and looked at it and saw that Valvoline had over tightened the transmission fluid plug and cracked the transfer case.
My mechanic suggested he fix it with a JB aluminum weld as a temporary fix to save me money instead of putting on a new transfer case. He did and the weld has held well, but the transmission now feels like its lagging and slipping a bit and my check engine light is on and a light comes on that says Check Transmission and Overdrive clicks off and is unavailable.
Valvoline has now agreed to pay for it to be fixed right. Their chosen mechanic says the fix is to remove the cracked and welded transfer case and replace it with a Jasper rebuilt transfer case.
Is that the proper fix? Will that get rid of the lag/slipping transmission? Is that lag/slipping due to loss of transmission fluid due to Valvoline cracking the transfer case?
