Oh yea ?
What would cause the Jeep to snap/pop/clunk whatever you want to call it underneeth when driving at slow speeds 10mph and under then releasing the gas pedal as its about to shift into 2nd ? Both my 5.9 and our 4.0 do this, and so do other ZJ's i've driven..
The 4.0 has done it since we got it used with 20k miles over 11 years ago... this must be some kinda ZJ thing.. I always wondered if it was the transfercase snapping back due to the transmission not being allowed to shift because you let off the gas too soon at those slow 10mph and under speeds. Altho sometimes it does it when your rolling at those speeds too, right as the transmission shifts itll clunk underneeth, like there is some play in something and its snapping due to tightening back up.. Its so wierd, i know it isnt u-joint related
