Message on dashboard stating “service required so not shift gears. Visit dealer”
Had in 5 times for trans repairs while under warranty. Just out of the 100k warranty and it’s back at the dealer for that 6th time because the trans case is still leaking and trans body value failed for that 2nd time in 1.5 years. Very frustrated and feel the transmission is bad and should have be replaced, but dealer kept saying it was fixed. Thoughts?
Anyone else having these issues?
summary of repairs below, although I’m pretty sure this issue was happening much more than I was aware of.
9/2020 miles 61k. Trans case fluid leak -radial shaft seal ring and input flange on transfer case seal repaired- under warranty.
1/2022 miles 80k. Trans case leak. Radial shaft seal ring and trans case seal replaced
9/22 miles 89k. Trans shifting horrible. Do not shift gear notice came up on dashboard. Replaced leaking park prawl actuator threaded plug. Replaced trans case adapter gasket, trans body valve -reman ctrr unit electrohyd and input flange on trans case seal.
9/23 miles 103k. Leaking trans fluid from trans case coming from lock prawl plug.
3/24 miles 110k. Leaking trans case. Lots of fluid on underside of vehicle. Trans body valve failed again and needs to be replaced.
