I posted something on my 89 automatic the other day with minimal responses. No problem.
Now I ask this; has anyone here experienced any slippage that was corrected with a full flush?
I ask this because a full flush is going to cost me $100!! I don't want to spend this kind of money unless I know it will work.

 

it should, if you dont have any maintenance record for oyur car or if its got a craploada miles, id definetly do it it should give your tranny more miles to live with, and it will probably help the slippage, but slippage, without knowing a whole lot, its probably something a little worse than the fluid

 

below is the original post. just as an fyi, the current tranny has about 125k miles on it. it had 118 when i bought it.

did you do like Matt said and take it to be checked out?

If you don't want to spend the money for the full flush, you can do it gradually yourself. Not as efficient, but after about 2-3 times, you can basically cycle through most of the fluid. All it amounts to is draining the tranny, measuring how much fluid comes out, and replacing that volume with fresh fluid. You won't get it all out just by draining, so you need to do it a few times. Drain, add new, and drive for a while. Repeat the process a few times and you will cycle through it. Again, it's not as good as an actual flush, but it's better than nothing. It's discussed in more detail in other threads, so I suggest you search to get the exact procedure- i.e. volumes, etc. When I did mine last week, I got about 2 3/4 quarts out.

 

Pressure flushing a trans that has not had routine matinance can potentially be fatal to the trans.

 

Don't waste your money. Flushing your transmission is not a FIX, it's a maintenence item. It's something you do to prevent trouble from happening. It's not something that will fix problems that have already occurred.
