Shifting Funny

[jwibbity]

Well I've noticed in the past week the trans has been shifting funny and progressively getting a little worse everyday.(At least i think its the trans) When accelerating at about 1/2 throttle it seems to shift quickly up to third and then stumbles into the TC lockup (hangs around 2K for a couple seconds then shifts into OD). When coasting (OD locked) in 3rd and 4th I can notice a certain vibration, more like grinding noise and when i get back on the gas it stumbles a little.

Haven't checked fluid level but it was changed sometime in 2012.....cant find the receipt

Trans was rebuilt at 61K, I am currently at 81K.





Is there anyway to eliminate this being a possible engine issue, I currently have no CEL's or codes, OD light is not blinking or anything

Does it feel like driving over rumble strips? Are you sure whoever changed the fluid used Mercon V?

when coasting yes it does...... and as far as i know yes, the shop was an ASE certified shop highly recommended by car shops and dealers in the area

But did they use Mercon V? Could have used other fluid and added an additive to "make" it Mercon V.

Check the fluid level.

Where I was going was the infamous torque converter clutch shudder, but that only happens on acceleration, not coasting or decel, and I've never heard of a misfire being felt on decel either.

Sounds like you have something more unusual happening...

It shifts rather fast and jumpy on acceleration, and sounds like it grinds on deceleration and coasting, but only in 3rd and 4th when the TC is locked, my A/F gauge pegs at 17.0 when coasting in 3rd and 4th, and stays at 14.9-15.0 when coasting in 1st and 2nd

#1, Check fluid.
#2, Don't worry about AFR on any deceleration. The PCM tells the injectors to shut off on coasting in a typical tune. CFSO (Coasting Fuel Shut Off)
#3, The fact that 20k ago this trans was rebuilt is a bit worrisome. Who did the work and what was done?

a place called coastal transmission in beaufort sc, it was a complete rebuild

checked fluid and it wasnt even reading on the dipstick and the very end of the stick had little pieces of black stuff on it (wasnt metallic more like paper)......
went to autozone and added about a quart and a half before i got it into the crosshairs on the dipstick, car feels alot better now, but still seems to stumble a little engaging OD

is there anything i should look at replacing inside of the transmission since its been running like this for almost a year, probably the OD band

Sounds like you are in for another repair. It wont be cheap.

Check your fluids!

yea!!! well my pell grant money should be rolling in any day now, guess i can rebuild the tranny again

i was going to put that towards a forged shortblock.......

Isn't a Pell grant supposed to go towards school? Hmmm we didn't qualify for anything for the wife for a Pell grant even... Pissed me off.


Black material is a bad sign. I agree with Zach, rebuild is in order without a doubt. If it's not a near term solution drain / change filter / new fluid at a min.

usually it is but since my schooling is 100% payed for through the VA the pell grant comes back to me as a check

and should i get a complete flush of all fluid or just a drain and refill???

Thread hijack on.

If you don't need the Pell grant for its intended purpose why take it?

THIS THIS THIS! We can't get any financial aid and people do this...

Done on that rant..


Do not flush it, just drain / change / filter / refill.... heard of more issues from flushes then change / drain...
