well this is my second transmission(i kept the first one incase i ever needed a rebuild)
problem started last week, the first run of the day, i get onto the road but down the throttle 1/4 ways like aways, but when i think its going to shift into second doest, and im kinda waiting for the shift into second buts its like the car is thinking bout it... and you can feel the car want to shift into to second....then when it does it reallly really slow shift like i can feel it engaging. shift from 2-3rd isnt very good either. once the car warms up a lil bit the car shifts find, just the first time it shifts it does not like it...
only other issue i have is when i start the car, it revs about 900-1000 rpms and rpms climb and drop a few hundred rpms, i sit and wait 1 minute and slowy/ gradually the rpms drop to normal rpms... and my throttle is stuck and i have to "tap" the gas once and its fine after that.....could this be my issue?
I had the issue with my throttle being stuck after sitting overnight. You throttle body is dirty and needs to be cleaned. I recommend taking it off the car and soaking it in some throttlebody cleaner and scrubbing the TB walls with a toothbrush, I did that with mine and it came out looking like new and the throttle is much smoother now.
thinkin it could be my issue with my laggy shift when the engine is dead cold?
going to by tb cleaner ad maf cleaner, can i use the maf cleaner on the iat??
The laggy shifts might be a dirty MAF sensor, clean that with CRC MAF cleaner, also check your air filter. Your MAF sensor plays a role on the PCS and the amount of pressure your tranny applies during shifting I am 90% sure. Make sure you take that throttle body off and scrub the hell out of it. Remove all sensors from it. The only sensors you can really clean are the MAF sensor, and the IAC. I cleaned my carboned up IAC with basic throttle body and carb cleaner and its still working fine to this day. Do that and while you do it, disconnect the battery to reset the PCM for the cleaned up throttlebody. That may be unnecessary but if its really dirty, it cant hurt to have it relearn the newly cleaned TB.
Usually it's when it's warm because of the warm fluid or a clogging cat. Yeah you can use MAF cleaner on the IAC. You'll see, it's kind of like a spring that is probably covered in carbon so once you get that carbon if it should work better. If not they aren't that expensive to replace (unlike the MAF)
k gonna clean up the TB and sensors, if it continues after that ill get a video, thx guys.
EDIT: what should i get
