again and it was running good for
about 15 min and then it started to
go slow I was going 70mph and I
could only go around 50 and I stop
and checked trans fluid and there
was a little of fluid in it I put two
bottles of trans fluid and took off and

and he has to rebuild the whole
transmission is it true ?

I'm not looking at the trans, but based on your descriptions, there is probably some internal damage to some of the components. How many miles on the transmission, over 120K? If you were low on fluid, that tells me there is a leak, and running low on fluid overheating the transmission is a bad thing. Then yes, your mechanic is right, parts need to be replaced, and when your replacing some parts, you usually replace all the parts so they can warranty the work, so a full rebuild is necessary. HTH's.

It also could be a electrical problem. my 94 W/T would not shift also turns out there is a computer that tells the transmission when to shift look at that before you spend $1800.00 on a new tranny. forget a rebuild.

Check the color and smell of your fluid. a dark(almost black) indicates a burnt out 3-4 clutch pack. A red and oil smell would indicate an electronic issue.
