Ive come to the decision that the TC on my 95 zj is taking a crap.

I want to replace it but i dont know how to identify which one it is.. i crawled underneath and didnt see any ID markings at a glance. What TC do i have?

Ive seen a few on ebay for 300-400 dollars and dont mind trying a used one.

Also, i found a rebuild kit for about 100. Are the rebuilds on these difficult?

Any help is appreciated, thank you.
