Went from the 21' model With 130,100 miles to a 24' with 6069miles. 24's dont have that bypass on the transmission heater .. mweh, the transmission was almost identical in price to what all the parts would have cost to fix current transmission . It wasn't worth the hassle .
…Or wait until you install an innocuous upgrade and they void your warranty, then never look back and let the modifications begin…
I was getting a TCM communication failure code . It is a purely computer/electrical component failure.
Yep mine did that for 20k and was easy to live with, never threw a code till it stopped shifting into reverse . It takes 3 times consecutive before it will throw. At least thats what mine did.
If I would place back in park sometimes turn it off and back on or run through all gear or drive forward then go to reverse it would. After failing 3 times . Would have to clear code then it would. My problem was much more advanced than yours. I literally did not have another vehicle to use
. And saving up for what I needed and ordering it all etc.. let it get even worse.
And each situation may be different, depending on the exact location of the cause.
No, @ 89,000 I had it changed at the dealership. I was going to do it but I work 6 days a week and I also didn't have a big enough catch pan or a fluid extractor at the time. ( I sure do now) .
can't flop that pizza in the floor Wifey would chop my .. well enough of that .. I have had that thing in every situation you can think of even near tipped it over , rear wheels off the ground jumped it a tiny bit slammed against the stops numerous times( bent steel rims on one occassion)
