Question about Jeep Cars & Trucks

My 2002 Jeep Wrangler 4x4 Sahara lifted has black transmission fluid as if it has never been changed and now has 125,000 miles. Should we change it?

My mechanic discovered that the fluid was black when he changed out a hose that had a slight leaking. He says he is afraid to change the transmission fluid since the jeep has over 100,000 miles 125,000 to be exact. We bought this jeep for my son in April 2015, what should we do?

Black oil is burnt oil and indicates several things
1-- excessive loads being applied to transmission ( heavy work or trailer being towed
2--- excessive vehicle speeds
3-- transmission mechanical problems
4-- low pressures resulting in band and clutch slipping
5--- transmission not shifting ratios correctly
before you change the oil run the fault codes to see if there are any recorded faults concerning he transmission
to change the oil the pan has to be removed to clean the filter so have the internals checked and the bands and clutch packs adjusted at the same time
Have the work done by an accredited transmission specialist shop and get quotes before hand
oil should be changed around the 60000 miles mark or earlier depending on conditions of operation

SOURCE: how to change transmission fluid in 2005 jeep

Most have a drain plug on the pan. to do a simple change, just remove the plug and drain it, then re-fill. to do a filter change, you need to remove the pan and the filter inside, remove all the gasket material (or it will leak) and put everything back together. There is no provision for draining the converter so if you want to do a better more complete change, drain from plug, refill, drive a few miles to circulate new fluid, then do a complete change with filter. You won't get it all out but a considerably larger portion of the old fluid will be removed.

SOURCE: 2002 Jeep Wrangler, had a slight tranmission leak,

There is air in the lines...start the jeep, pull the tranny dipstick and shift the jeep from D1, D2, D, N, R, P and back....assuming this is an automatic...and repeat until noise is gone. Don't forget to check the fluid level and replace the dipstick.

Transmission fluid is almost black

1st your sure your not looking at the motor oil instead (that color is not good on motor oil either) , but if your sure your looking at the transmission fluid then id say that trans has problems ! a fluid /filter change is the place to start , but if that's no good and trans still doesn't work well then a rebuild is the best way to eliminate any problems

I have a 2005 Cadillac deville and the trans hot idle engine has been coming on. I then discovered that the high pressure hose to the transmission is leaking badly. The car will not shift past first gear....

Check transmission fluid level first. How long since it's been changed? Make sure to use owners manual to check correctly. Usually hot, idle, run through gears first. If low, could cause all those conditions.

I have a break leak and coolant leak. I know this because both fluid holders I've had to fill; now it's hard to shift. How do I fix these?

you will have to check for were the brake and coolant is leaking from by looking for the leaks.with the brakes it could be the lines a wheel cylinder a flex hose even the master cylinder itself.once you have found the leak replace the affected part and bleed the system.with the coolant leak look as well and you might have to fill the system and pressure test the cooling system to find the leak then repair as needed.the shifting check the transmission fluid level and condition it should be a redish colour and not dark brown or black and not a burnt smell to it.if it does then you may have a transmission problem that will have to have a shop repair.if its just low and slightly dicoloured changing the fluid and filter may take care of it.

suggest that you check your transmission fluid post haste please. you may only need to add transmission fluid to your car. also,if you have to add the fluid,where did your fluid leak? check for leaks under your car when parked. you may need transmission fluid and filter change,suggest that you do this with new filter and add lucas transmission treatment to the fluid change also. you'll need to purchase this yourself,unless you have a mechanic in the family that can do it for you.if not i suggest you find a mechanic you trust,then tell him,or,her to add this to your tranny fluid change. also suggest while the mechanics there at the transmission to check the modulator valve on the transmission,and the vacum line that operates it. just a hint. thanks for choosing

My transmision fluid is black and two transmision mechanics say if you change transmision fluid the car wont run no more is this true sombody please help me they are saying im going to need a new...

The mechanics lied to you. Changing the transmission fluid and screen will not cause any car not to run. Just as you need to periodically change the oil, the same holds true for transmission fluid. Though the fluid is black, yoou state that you have no slippage or nothing out of the ordinary. If that is the case, then you do not need a new transmission. Just have the fluid and screen replaced and all will be fine. Make sure to pick up a transmission pan gasket while you get the necessary fluid and screen. Again, changing the fluid will not cause any car to not run. It is safe to perform the fluid change.

Red fluid dripping from bottom of car, is comming from a black cover (maybe transmision oil?)

Red fluid it auto matic transmission fluid. The black cover is the bottom of the transmission where the transmission filter is. Most of the time.. unless you recently had the transmission filter changed is inthe hose area where the hoses fromthe radiator connect to the transmission.

It is still quite possible for your transmission pan gasket to be leaking. Most of the time people think that by just tightening up the bolts that they fix the leak when in fact the over torque the boltrs and it leaks even more. If the transmission pan gasket is leaking buy a new gasket making sure the bolts are tightened per the manufactures torques.

Thanks for using FixYa.

Dumped all its transmission fluid is the rear seal

Could be the rear seal but for the oil to come out that fast it is usually under pressure--Check ur cooling lines-if they are ok u might need a front seal.
