Transmission problem

[cousinles]

I have a 1997 Chevy Lumina with 173,000 miles and when I am going around sharp left hand corners the transmission slips quite a bit.Somtimes it take like five soconds to recover itself. I checked the fluid and it is reading full if anbody could help me with this issue it would be great.

That's funny you say that, because I posted that my 1997 does that sometimes on a hard left if I stomp it and it tries to downshift in the turn it'll wind out and won't hook up until I back outta the throttle...It hasn't done it since I serviced the tranny last year...I dunno, weird...

maybe ill try a filter and fluid change with a little tranx and see if that helps.
I guess it cant hurt.

[tblake]

could be a partially plugged filter on top of the g-force going into that turn and given conditions causing fluid loss to the shift solonoids. Maybe????

It could also be a filter which is not securely retained, and G forces tip the filter so that the pickup tube seal allows the pump to suck air instead of oil. Either way, pulling the pan and changine fluid and filter can never hurt unless something goes terribly wrong.

I know this is a couple of months old, but mine is doing the same thing, after a right turn though.

This along with some other things I posted on a thread titled "Weak low rpm, good high". At low rpm it boggs from part to half throttle, then takes off. Then after it shifts it boggs again and then takes off again.

Have checked everything, and will finally get a scanner with monitoring capabilities tomarrow.

If anyone has anything else on this topic, it is appreciated. Roan. 97, 3.1.

neutralling on hard left turns is a common problem on almost all front drive chevys with this trans. service the trans, and overfill it a little, past the cross hatches on the dipstick up to the bend in the dipstick, about 1 quart over. This will cure this problem.. Poor design sump, is on passenger side of pan, and hard lefts cause the pan to suck dry, pump cavitates(sucks air) and trans neutrals out. Hope this helps, thanks moyer5000

Not true on the later model transmissions, but yes back in the 80's and early 90's, yes could be. I am going to lock this thread it is too old, start a new one if there is continued discussion.
