Good to know yours made the same noise. There is a transmission shop with a good reputation close by, so I might give them a call tomorrow to see about a rebuild. Would be great to baseline it and get some miles on the rig after more than a year in the garage. And I pulled the t-case off at the back of the adapter, so haven't taken a look at the main seal yet. Hopefully tomorrow if I can find some time.
See if they can beef it up if you do the rebuild. Always better to be safe than sorry. Im sure they could build it up for less than what a 4l75e would cost
Shifting the Tcase? If so mine is the same waySo question and a comment. I have had a 4l60e in my fj40 for 7 years. I cannot shift it while the engine is running. I actually haven’t tried to shift it in park. I will try it out this week. If it’s possible to shift in N i am all ears.
I would love to figure this out. I am half tempted to go back to a 5 speed.
