Hard shifting

[r3kU]

Can someone analyze how its taking forever to shift could it be this tranny is dying? What do i need to do

98 Eclipse GST Pull - YouTube

The video was short and it looked like you where going WOT on your drive.

 

[r3kU]

Yeah i was it was a pull, but just normal driving lately the car shifts hard and downshifts uneasy, when i would come to a stop the car would almost want to stall and the rpms drop really low like under 800 its like bouncing from 700-1000

 

[dans95dsm]

Sounds more like a vacuum leak to me.
My car idle surged like that, and the owner before had the bov vented and it felt like it wanted to die
, but then i recirculated it. now it stays a little steady at 800.

 

[r3kU]

Interesting it could be a vacuum leak, My car died on me like 8 times today coming to a stop

 

[dans95dsm]

is your blow off valve vented or recirculated.

 

[r3kU]

vented meaning releasing it to the atmosphere if so then yes

 

[dans95dsm]

that contributes a lot of the reason it stalls on a stop.
stock it comes circulated, when it vents the computer doesn't know what happened to that air,
for that reason it throws more fuel in the engine causing it to stall.
The idle surge can be that and a few more things.

 

[r3kU]

Solution? Fix vacuum leak, Im just curious if it would be the tranny tho

There is a T fitting that one side has no line because I took it off it was for a boost guage that's not running

 

[dans95dsm]

it would be hard to tell if you have those other issues interfering.

 

[r3kU]

Could you evaluate on the BOV the difference between vented and recirculated

 

[dans95dsm]

the hose connected to the blow off valve shows an example of a recirculated bov

 

[r3kU]

Oh okay so without it it would be vented?

 

[dans95dsm]

yea, the air needs to go back into the intake.

 

[r3kU]

So you suggest upon recirculating my bov ?

 

[kenjiw]

So you suggest upon recirculating my bov ?

yeah, what bov are you running?

 

[r3kU]

Some ebay bov just says Type RS and soft and hard

 

[buhay6]

So a knock off greddy rs. Definitely recirculate that as unless you have a means to tune to eliminate the ecu anticipating the release of excess intake pressure from the bov, then you'll have no choice but to recirculate it. If it was something like the waste gate on your turbo then it wouldnt matter but its not.
The reason it could be related to yoru shifting issues is because your tcu gets its information from the ecu. The ecu is anticipating something its not getting.

Where to start? Did you open a port in the intake for the bov?
Is there any instructions out there?

Thats a problem..No recirc on intake..Ok heres an idea..Put up a want to trade add.Trade your non recirc for a recuirc hard pipe.


Youll also need a diferent out on the bov,that one is for venting only

Also on the adapter for the filter..I siliconed some of it, because the adapter was still letting in non filtered air..

 

[r3kU]

So id just need a hardpipe and a hose and some clamps ?

and a new bov..?

 

[shifty2006]

Mine was the same way when I got it yes you need a recirculating bov an intake with a recirc on it a hose that goes from bov to intake and two clamps to clamp the hose. You are losing metered air causing the car to think its getting more air then it actually is so it will add more fuel. Look at your plugs they are probably either wet or pretty covered in black you will love the difference when you fix that the car is a lot happier. Some people just want the pshhhh sound so they vent the bov to the atmosphere but if your running the stock airflow sensor you need to be recirculated. Personally I would do what he said and see if anyone wants to swap hardpipes for a recirc and then I would just get a 1gbov

find a fab shop near you and ask them to add the connection for you
