    I'm tryin to figure out what is wrong with the K5. It has a bad vibe through the first 2 gears (700r4) then settles off and runs normal. Some say it is a bad torque converter. But I have no clue.The fluid does smell a bit burnt. What should I do? Comments?

    That doesnt look too bad.A bad torque converter wont cause vibration.

    Not anywhere near what the new fluid smells like. Smells kinda like burnt metal or burnt hair. Has a nasty smell. I don't wanna pull the tranny to find out it was something else. I'm /forums/images/icons/confused.gif /forums/images/icons/confused.gif /forums/images/icons/confused.gif

    That smell sounds like the friction disks material when it burns off, the vibration in the first two gears would lead me to believe that they are chattering due to wear. Does is slip and rev high or just chatter (vibration). Has your engine temp come up at all lately?

    Haven't noticed a change in the temp (scared to drive the K5) It doesn't make a noise,just shakes a bit then smoothes out.

    Yes it is burnt or wore out.That fluid looks like SH$$. Change it. Do a complete flush. The fluid in a 700r4 should always look like new. If it gete even a little discolored it should be changed. I dont know if that is the vibration problem or not. But running old burnt wore out fluid is the fastest way I know of to wear out a auto tranny. ATF should always look pink and new if you want your tranny to last.

    Re: Does this tranny fluid look burnt?

    take your rig to a jiffy jube or something like that....most places like that offer a flush of the entire system (tranny,filter,lines,cooler,torque converter).

    This is a little pricy (&amp;80.00+) but i could fix the problem. (i used to work at one so i've done these and it did help)

    Just a suggestion

    I don't know where you got that information. A bad torque converter can and most likely will shake like hell. Especially when it is grenading from the inside out.

    Re: Does this tranny fluid look burnt?

    My advise is to drop the pan and take a look inside. Look for pieces of metal or chunks of band material. A buildup of fine dark grey stuff on the bottom of the pan is normal if you have a lot of miles on it. If there are pieces of metal or little chunks of stuff in there plan on getting a rebuild soon.
    If you want to flush your tranny yourself and save 80 bucks heres how:
    its handy to have a helper to do this.
    Disconnect one of the cooler lines and route it in a bucket.
    Start the engine and pump out the old fluid while adding new fluid to the trans. Dont let it run dry!!! Start /Stop the engine as needed. Always add as much fluid as you pump out.
    When the fluid comes out looking new and clean you are done.
    hook the cooler back up and check the fluid level and add fluid as needed.
    Plan on using 2- 3 gals of fluid.

    Burnt fluid will taste very different from fresh ATF.....

    You should try a teaspoon of each and report back with your findings.

    Re: Does this tranny fluid look burnt?

    Since the converter is physically tied to the motor, wouldn't problems ONLY until second gear be rather strange if the converter was at fault?

    I've heard of *noisy* converters, which make noise in neutral or park, because the bearings/thrust washers are worn out, but a 2 gear only vibration doesn't *seem* like a converter problem.

    Re: Does this tranny fluid look burnt?

    I have done the at-home fluid flush, too. It is really easy if you have an extra oil cooler on the tranny with rubber lines. You can just hook up an empty gallon jug with the line going into it so that it is easy to see how much has come out. You can turn off the engine for jug changes. If your fluid isn't too bad, 3 gallons pretty much changes all of it.

    The forward clutch is engaged for gears 1-4. Shifting to 2nd just applies the band. The shift to 3rd releases the band and engages the 3-4 clutch. Overdrive is just reaplication of the band. I can't think of one single part that would shake in 1st and 2nd, but not 3rd and 4th. Maybe the input reaction shell?

    Maybe it's not the tranny. Maybe it's in the driveline or the flexplate to torque converter bolts are loose?
