Auto wont shift into 3rd

[theKnifeArtist]

i took my car out for a drive just now after putting my vacuum line on my bov that i was missing...i dont think it has anything to do with this...or could this be a vacuum problem? at first it was all good driving soft and hard, and then... when i put my foot down, it would down shift, go up to 4000 and it feels like something is pulling it back and preventing it to go higher or upshift. i could be wrong on what i feel, im gonna take it out and drive it again in an hour.. any thoughts? this tranny has like 40,000ish on it.

What he said^^^^^^^^.................

 

[theKnifeArtist]

so i disconect the ect and drive it manually?
how far do i have to dig to find that ect..
so how do i distinguish if the ect is broken or the solenoid is broken..

ECT is in passenger kick panel. In front of the TEMS computer

i dont understand this...in the chart..in position 2, it says gear 3....im supposed to be in 3rd gear when its shifted into 2?

 

[tookwik4u89]

yup, 1 connecter , real easy. If it is electrical, you will have to go through some troubleshooting by tsrm to find the cause. It is usually mechanical though! I have heard of people on here have ecu problem, and solenoid also, but personally, every bad one i've seen is bad trans.

 

[theKnifeArtist]

oh boy, ill do the test tommorrow.
fuck.
this sucks.
this would be a good excuse for do a 5speed swap if i had the money this time..

I'll post some pics of my damage on the black car tomorrow, wont shift into 3rd very easy, slipped in 2nd and 3rd.

 

[theKnifeArtist]

what kind of damage

 

[tookwik4u89]

Clutches go bye bye!

 

[theKnifeArtist]

did this happen all of the sudden like me here? or did it slowly crap out

 

[tookwik4u89]

mine went from delayed shift to slipping hard in a few days, hard to tell by your description though, what happens if you stay in gas, revs higher but no go faster?? What does it rev up to?

 

[theKnifeArtist]

no it revs and stays at 4000 and feels like its being pulled back to stay a 4000. i didnt hold it at that for a while cuz it really felt bad. more info tommorrow

 

[tookwik4u89]

That doesnt sound like trans issue to me.

 

[theKnifeArtist]

ill do some more testing tommorrow, even maybe make a video..and ill do that ect test. im not getting into 3rd, how is that not a trans problem? the desciption from that other thread fits pretty perfectly

 

[tookwik4u89]

I just dont get where if its in 2nd its not revving over 4000rpms, unless you mean you back off at that point because its not shifting. When they are in early stages of failure, often times backing off will aid it in shifting, when theyre gone, you have to rev the shit out of it to get it to the next gear.

 

[theKnifeArtist]

no i wasnt lettin off..ill explain further tommorrow. thanks

 

[theKnifeArtist]

whew! you were right, it wasn't a transmission problem at all. it was just one big ass boost leak(the stock bov port off the 3000 pipe...my "plug" totally fell off) i didnt see it last night cuz it was too dark.
she's runnin' fine now, thanx for the help

 

[tookwik4u89]

LOL...cool man, glad you got it fixed, took pictures of my trans fun today...
