242 or 249?

 

242
So..
Jeep decided to start acting like it was pulling off on 3rd gear..no power till it shifted (at a high rpm)
Threw a code (p1757) which is obviously fairly common

Points to the governor pressure sensor in the trans.
All the threads I've read say to just replace the sensor and the governor solenoid and bingo.

Anyone wanna assist with this? Looks like just dropping the trans pan and removing 4 bolts to the housing which holds the solenoid and sensor
..
Then simply swapping in the new parts.
I guess I could pop on a new trans filter while I'm in there.

 

WJs never came with a 249, they had the equally bad 247.

 

This.
247 or 242

 

He's very subtle in his introductions anymore!

 

It's not hard. I changed some on a Dodge truck i had years ago, takes about an hour, maybe two.

The solenoids i believe are a dealer part, not super cheap. Also, if that tranny calls for Mopar+ (I think) tranny fluid, I have about 2 gallons I'll make you a deal on.

Easy job.

 

Haha. Looks like a green light on a part out by the way

 

Think you may have some free time to help me tackle it?
The solenoids aren't a dealer only part..several websites have them..Borg warner sells a "HD" OEM replacement..
I'll probably just order one transmission parts. They seem to have decent reviews.

I think the 42re requires rtf4

 

ive been told its actually worse to just swap a filter on a trans, but more commonly done with your just rebuilding it. Ive got family in the transmission business ive been told this more then you can ever think.

 

I was always taught if you change a filter and fluid from the time it's new on a regular basis it's fine but if it's got a good bit of miles on it it's best to leave it in there.

 

The issue with changing fluid and filter is the new fluid's fresh detergent. With old fluid it has lost it's ability to really clean, but new fluid will really start cleaning again, and can cause problems. Of course it's all theoretical mechanics. It might or might not hurt.

From a tranny shop's perspective, only the fluid/filter changes that then fail show up there, 100% of them. What percentage of the total fluid/filter changes does that represent though? 50%? 20% 80% I'm just asking for conversation's sake.

 

I've got something I'd like to see modeled in Solidworks for myself.

Starting with a run-of-the-mill long arm crossmember (2x4 rectangle tube), adding a skid plate extension on either front or rear of that crossmember, what kind of additional torsional stress is placed on the crossmember and mounts should the Jeep drop down on the ends of that skid? Say the skid is 12-14" long.

I foresee soem pretty good unibody dmg at the crossmember mounts being possible, or breaking/bending the crossmember. Just curious on some theoretical numbers there. Let me know if you need more info or a model.

 

i need a good long arm setup that can with stand my right foot.

 

Brians.....

 

No such thing, that's why I don't have one either. We need to find a good source for unobtanium to build some out of.
