My 95 olds cutlass v6 3.1L sometimes wont shift out of third gear and it just completely shut off on the thruway... what does this mean?

Get them on the phone first & go from there

Sounds like a shift solenoid problem. If you have any codes associated with solenoid failure, that is probably what it is. If there are no codes, it is probably something stuck in the valve body or something else mechanical.

change the fluid and filter add new fluid and add lucus additive

the trans needs repairs it could just be a valve body
solenoid problem or a more internal problem if it was me
I would by add a Lucas oil trans additive first then cross ur fingers good luck this stuff sometimes works wonders to delay a needed repair

sounds like the vacuum modulator valve,have aamco check for free.











TIM....

Check your transmission fluid level You will need to top it up if low. Low fluids mean that not only will the transmission be slow to respond but when it engages gear it does so with a bit of thump. If the fluid stays low this thumping of the gear changes will eventually shear off the input shaft. Also check the linkage located from beneath the gear shift to the transmission casing and adjust it if necessary. My guess is that topping up the transmission fluid to its proper levels will solve the problem without need for any adjustment

you have to pull down the oil pan of the tranny. then take out the strainer inside attached to the tranny. dirt is clogging it making the sometimes shift and other not.

When in overdrive engine is locked up with trans. so engine performace is more pronouced ,I would think a tune up would be in order.

sounds like a relay to me. but you can get oil for gear box that frees berrings.

when you say it wont shift out of first gear what do mean it stays in first the whole time or it goes into like a nuetral state
