Latley my RPM's have been fluctuating. Sometimes when I'm stopped at a light with my foot on the brake the RPM's will jump from around 500 to 700 or a little higher and hold there and sometimes it will drop back down to around 500. Or even sometimes when rolling to a stop it seems like the tranny isn't kicking down the RPM's will hold around 700 or a little higher. Today for the first time my car died at a drive thru. Tried to start it back up and it chugged a little bit and started up. I pulled forward a little bit stopped with car in drive and foot on brake and after about 2 min of waiting behind a car in front of me it died again and this time it took a lot of cranking and car chugged a whole lot then finally started back up, but barely. I thought the problem was the IAC motor but that wasn't it nor was it the TPS. I know my tranny has been going bad for sometime now, it has been making a buzzing noise while idling and it shudders in OD but now I'm starting to think it is really going bad. Could these be symptoms of a tranny gone bad or what??

 

anyone??

 

Could be.

Are you getting any SES lights while it's running? In other words, is it setting any trouble codes? Does it have any problems in neutral? Have you done standard things like plugs, cap, rotor, wires, fuel filter recently?

 

last post deleted...I didn't read the whole thing. LMAO

Try manually moving it to first when you stop. If it's the torque converter, it might kick out when you go down a gear, and it'll also let you know if the tranny is sticking in gear.

When was the last time you changed the filter and fluid?

Sounds more like a problem with the Torque Converter Clutch solenoid if it feels like the tranny isn't kicking down.

 

The day before the problems started I degreased my engine compartment. I don't think this had anything to do with it since the symptoms developed the day after. I also filled my car up with cheap gas later that same day. I didn't want to but had no choice at the time. Would a clogged fuel filter cause symptoms like these?? I'm not getting any SES lights and as far as tune ups go I will have to look at my note book, but I don't think it's been too long.

Hey kd5boc by shifting it down into first manually you mean moving the shifter to L1 right??

 

Yep
