To those that rendered their advice to my inquiry re Jeep Wrangler Unlimited CRD Turbo Gear Box. I was querying my Gear Box. I thought I had a 3 speed box with Automatic Overdrive. With a check at the dealer I find the I have a 5 speed box as below.

The Gear Box is the 545RFE with ratios of
1st - 3.00:1
2nd - 1.67:1
2nd prime - 1.50:1
3rd - 1.00:1
4th - 0.75:1
5th - 67:1

It works out that I have a three speed gear box with two automatic overdrives. Witch only activate on acceleration for overtaking. The second work as a smoother kick down when on a incline, for fuel efficiency.

I find it hard to believe that these are working gears, as would work in a manual gear box. But I have to except that the insurance company's will only regard it as a Five Speed Box.

I appreciate the input that I received from Members on this subject.
