Help for my tranny

[shill1234]

I have done a search but everything I have read is for the first gen cars,my 97 is kinda acting funny and could use some help.When I drive it hard everything seems to be ok,but if I drive it relaxed it does some weird stuff in 3rd and o/d. The carseems to hunt/and slip in the gear that its in.When cruising under light throttle in o/d the car seems to slip a little i can watch the revs only rise about 400-500 rpm,it seems like it is going in and out gear.Is it tranny time or possibly shiftkit/chip time?Thanks in advance for any
help.It only seems to do it right after it shifts into gear ,after it does it it won't do it again until another shift.

i would get the tranny flushed and then have the fillter changed first see if that works

very common. It's the torque converter locking and unlocking. This is also why Mercon V was developed. do a search to read up on why Mercon V was introduced to elleviate the stress on the frictional material/TC issues.

Furthermore, the factory TC lock-up schedule is way to low(37mph). It feels alot like shifting a manual tranny into 5th gear at such a low speed.

many use SCT programming/ECU flashers/etc to correct this absurd setting.

ideally, a wide ratio 4-speed A/T like ours should keep the TC unlocked until 50 mph.

Now wait a minute, Craig. I talked to my mechanic and he flatly refused to flush my transmission; said it would ruin it b/c it's too old. He also said that I need a new tc. Now you're saying that it's ok to flush it and that I need to reprogram something? Are you sure this isn't an O2 sensor issue?
