I've had this jeep well over a year(2000 miles max though) and till now have actually never given it full throttle.
I drive it like an old-man because I am kinda old(53)and want it to last.
I've had some "minor" transmission (solenoid) issues but they went away when I put in a transmission cooler.
I was merging into traffic the other day and for the first time ever went full throttle from maybe 10mph to about 50mph.
A couple of things happened:
1) I was duly impressed w/the torque at full-tilt from the 4.0 and this is coming from someone w/a late model 6.7 PowerStroke.
2) At near max rpm/power(or thereabouts) I got a severe vibration that disappeared as soon I let off of it a bit.
The vibration hasn't happened before or since but then I've not gotten into it again. In fact, there is zero vibration in other situations at any speed.
My assumption is that it's the Torque Converter. If that's the case I won't bother to address anything else w/the transmission till it stops going and I put a rebuilt one in it.
If it might be something else I may continue to nurse this 42RLE along as it shifts perfectly these days.
Actually, I'll continue to use it till it won't go at all either way
but if there is something I can do about it w/o pulling the transmission then I will.
The fluid level is just a bit above max when checked properly(Hot/Running/In neutral or park).
