Salad thanks for the advice. Since I only paid 700.00 for this Jeep and I believe the only thing holding the body together is the carpet I'm going to leave the RZR home.

thanks for the link, I'll keep that bookmarked.
although for my application I don't think I need it, what I mean by LED is really just a couple bulbs or strips that I'll place around the interior in order to get more light inside when needed (the bulb in the headliner doesn't do a really good job)
at first I thought I could use the current switch in the door that triggers the buzzer, but I would rather have a switch i can manually turn on/off when needed, I just don't know where to draw power (I guess looking at a diagram but even there I wouldn't really know what to do!)

Yeah, maybe on a new-fangled "hack me from my WiFi" technomobile. The only thing modern about XJs is that they have internal combustion lol.
(Also what is "pinion factor"?)
Noot quite. New TCM/TCUs might have that setting, but the basic decision is based on RPM, throttle position, and calculated engine load. (Engine load being a new thing, automatic transmissions existed long before computers). Road speed is irrelevant and doesn't change the internal gear ratios or how much power the engine makes.
Absolutely. With larger tires there's a LOT more resistance to movement than otherwise. Overall RPM is lower and engine load goes up.
The system doesn't care. The transmission programming is based on a power band. Change the axle ratio if you want different behaviour.

Pinion factor is just a variable they can adjust if the preprogrammed tire sizes are not available. It's probably set at 1 and then you have to do maths to figure out what to change it too. The dealer set mine wrong once and I had to bring it back to get them to adjust it correctly. Not 100% sure exactly what all they did.

On my new Jeep there are only 5 or 6 sets of pre-programed tire sizes they can pick from in the computer. None of them are on 15" rims. So you can either do the math and pick one that is close(in my case none of them were close enough) or use the pinion factor to multiply by and adjust to the correct size.

Yup...Weird new Jeeps. And only the dealer can access it.
Edit: Here's an old article on it: http://dodgeram.org/tech/mods/electr...ion_factor.htm

This thread is for all those who would like to ask something tech related and don't want to start a new thread or hijack someone elses, and for all those tech related questions you happen to ask in the big off topic threads. Me and some of the older members will answer every kind of question as long as it is TECH and polite.
P.S. for the newbs: stupid questions don't exist, there are only stupid answers. Feel free to ask whatever you want. "What is a Jeep?" is a good question....

2005 Jeep Grand Cherokee with the V8. The oil pan gasket apparently needs replacing (200K + miles). He took it to a small shop and he was quoted $900 if the pan needs replacing and *pinion* gasket (???) If the pan is good he quoted him $600 plus.
Sounds outrageous to me but I know nothing about working on his vehicle. I've replaced a few pan gaskets in my time but never had to pay more than $20-$30 for the gasket and that was the total cost less oil and filter.
9 hundred dollars????
Your advice and tutelage is appreciated.

Not my vehicle and once again I am asking for my brother who lives 200 miles away. I know little to nothing about Jeeps so your help is appreciated.

It costs money to run a shop. So let me explain this quote that seems high to you.
They quoted it with the oil pan because there is some times, where the pan can get damaged. And it's much easier to call a customer with a lower bill than it is to call with a higher bill.
Basics of in the end would you rather walk into a shop and get a bill for $600 instead of the $900 quote? All because the pan didn't need replaced.
Or would you rather get a quote for $600 and then get a call for needing to spend another $300 plus just in parts because the oil pan is damaged?
That shop is looking out for its self and customer. Just because $600-$900 seems high to you doesn't mean it is.
I did a oil pan on a v8 dodge van. It was a 96. It was a $1300 bill. You have to remove a **** ton of stuff to get it out.

I know bricks and mortar are expensive to operate and for the most part I think small shops do a good job at a fair price. No one works for free, at least not very long.
The quote was for 4 hours labor -total. An oil pan can be had for between $100-$150 (rock auto). Gasket kit around $30. With labor @ $80 hr I don't see $900.
My brother is not an off road type, it's all highway miles and unless the pan rusted through it's not likely the pan would need replacing, IMO, but I'm not there to see it.
Thanks for getting back. Appreciate it.
