Changed the fluid in the 99 sport tonight (and the filter) Solenoids test fine....Dex/Merc.
Changed the fluid a week ago...roughly 4 qts each time...brown the first time, less the second.
Daughter went for a test drive, said it seems improved but still happening..
(will know better tomorrow on her regular drive to work..).
I went out with her...and (apparently it's pretty predictable when it's going to happen)...there's a solid thunk when she's moving at a slightly slow speed in 4th...and gives it just a bit of gas to get it to shift to 3rd..
Feels like it's about where the rear seat is...(at least behind the driver/passenger).
Could something else cause the thunk...bad Transfer case, driveline U-joints, rear diff issues?
Shifting up is smooth...barely can tell as it shifts..
But it's that 4 to 3 shift that's when it happens...
Any suggestions?
Thanks!
