      If you replace the fluid with that kind of mileage it may start to slip

      Your call

      I would not replace all of it at one time

      When you get a transmission (more so for automatic than manual) with 150,000 miles put on the SAME fluid, you are virtually assured to have excessive wear, build-up and deposits in your transmission, which the detergent additives blended with new transmission fluid will loosen and break down, substantially increasing the risk of transmission failure (usually seal failure).

      Its not a "sure thing". In your case, it may result in nothing adverse, and you might drive another 50,000 miles before something goes wrong. You cannot say "at xx miles, this will occur, so your transmission WILL fail if you change the fluid and filter". But, the principle is sound, and the risk of failure is definitely increased.
      However, not changing the fluid and filter at all is a virtual guarantee of future transmission trouble.

      However, there are two schools of thought here: 1) routine maintenance is good, or 2) if it ain't broke, don't fix it. The thought of keeping the fluid as-is for extended periods of time is not an uncommon sentiment. The theory is that the fluid will contain deposits that can build up in the passages throughout the valve body. These deposits are akin to carbon buildup in the upper intake plenum. The transmission "gets used" to having these buildups, which are normal. If you change the old fluid, the new fluid will flush away those deposits, and the likelihood of changing the transmission shifting and wear patterns is high.

      Sounds like trans is slipping bad. Check fluid level and condition. More than likely its fluid is burnt which will require rebuild. Make sure fluid level is with in range. Check with engine running in park.

    It starts to shudder and vibrate when going up A small hill. only does this when going about 45 mph and light throttle.
    Going faster or slower. Or with more throttle shurrding stops.

      Have you had fuel pump or fuel injectors serviced lately? These are common causes others would say its your engine mount or transmission, but before you run to the mechanic saying "transmission or engine mount or fluids", think about whether or not if you ever had your fuel pump or fuel injectors replaced or serviced...just a thought..

    09 silverado 4x4 with 5.3 vortex. There is a vibration when shifting from second to third during shift.
    Wheel bearing is going. Vibration ends after shift but feels like it's coming from front wheel or transfer case

    Will my 88 700r4 shift without the ECM?
    got a 350 tbi im swapping to a carb setup. I was just wondering if my trans will still shift normally when I take the computer out or will I have to swap it to. I believe the 700r4 wasn't electronic until 94 but im not to certain on that. what other problems may I ...

      It will-- if it is-- a 700R4 & has a throttle valve & the cable going to the throttle body originally

      You can buy a bracket for a carb or use another GM Mounting bracket to work with a carb

      I believe your computer or ECM only was for the TBI Fuel Injection & you had a BCM for
      A/C & other body functions

      Your biggest issue will be going to inspection if you have that where your at

      So leave the exhaust converter on there

      With a carb I found your best to take out all the timing advance & let
      the motor fire late & have the converter do all the work

      That way you get good numbers at inspection on the CO reading
      Then set it back to whatever you want after inspection

      The other issue is how was it shifted into 4th gear?
      Any vacuum controls there--look on the radiator support diagram for vacuum
      hose & emission info
