first things first i would check the fluid level. if it is low it will take the converter a while to suck up enough of it to make it move. i would then check the filter. th350 has a pretty heavy filter on it so if it's plugged up it would amount to stator/sprag slippage in the converter due to lack of fluid. it would also in some cases cause hard shifting. if you think about it an automatic is a big hydraulic pump. it needs a given amount of juice at a given rate to make it work. if you try this and none of it helps, you've most likely got a stretched(ballooned) torque converter. the bands in this tranny only provide resistance for the rate of shift mostly(how hard or soft, and when to some extent, but very little). hope i helped. good luck.

sounds possibly could be torque converter, I would suppose if your bands and clutches are smoked it would be consistantly down hill (never getting any better)just a opinion (wrenchturner)

burnt clutches would cause the car to stall at stops, because they would'nt let go mostly. it could lead to hard shifts and take a while to grab and then suddenly hit like you were just rearended. i would say if you change using the same converter you don't see a change, then it's the converter. if you do, the whole inside of that tranny is meant to be made into a japanese car.

...so been smashing any mustangs lately with that tranny??? hahaha, just kidding. I would think that your best bet would be to just buy a cheap rebuild kit if you dont get the other tranny. Either way if it still slips, its going to be the converter.

Doesnt the 350 have a couple of external band adjustments?

The 350 TH has only one Band. It is Hydraulically applied. No external Adjustment can, be made.
Did You ever wonder what that Howling type Noise is when You have It in Low. It"s the Band applied, the Band simply keeps the Trans. from freewheeling in Low Range. Chances are the Torque Converter is full of Debris from the Trans going South. Rebuilt Converters are Cheap. If You rebuild The 350, get a Rebuilt Converter also. It will save You a Major Headache later. [ May 09, 2002: Message edited by: taz ]</p>

Does the fluid smell burnt?Or look orange?Try changin fluid and filter.Clean the pan and put a magnet in it.TH350s are pretty tough filter & fluid brought a couple back for me.
On one tranny that was real bad I started the car for 5sec. w/ the pan off to let the pump drain the converter.(Although this probably ain't ideal for the seal and pump.) Also does the car run hot automatic trannys hate heat.A trans cooler might prolong an old trannys life.
