JK Trans drain?

What were they thinking when they ran the exhuast cross over directly under the drain plug for the tranny? and why can't we use the same plug for the drain and the fill... not a 14 mm and a 17 mm....

NO COMMON SENTS!

I think it's so that you'll pay them to do labor for you.

I can answer both of those questions:

The exhaust runs under the drain plug because everyone's garage/shop needs to have the wonderful aroma of burning transmission oil.

In seriousness, as an engineer, I support the 14mm/17mm fill/drain strategy. When you are designing equipment for serviceability, having two sizes for fill/drain decreases the chance of error by users. If the service manual tells a person to 'remove drain plug using 17mm wrench, and then remove fill plug using 17mm wrench, there is a larger chance of the user removing the wrong plug. When I worked at a high clearance ag. sprayer manufacturer, the fresh water tank and the spray tank had multiple sized connections intentionally. It would have been easy to use the same connections, but would have added to user confusion.

It's the same strategy as making electrical plugs that can't be inserted 180° from required orientation, or to keep a farmer from connecting hydraulic hoses to the wrong quick connects.

Of course, I may be totally wrong, and it may be a stupid legacy design quirk like cigar lighters in cars (talk about an obsolete and ancient design). It may be that way because 'its been done that way for a long long time'.

Ajaxxx while it almost makes sence... as an industrial designer... I am not going to buy it! The fact that chrysler has a tool made for that one job goes to show that somebody screwed up... and the tool was not immediately avalible... KISS is always best but I apriciate your effort to explain it...

bubba2 did pretty much the same thing.

I made my own tool to remove the plug. If you want one I can make another.
