Update: 95 gsx slips with TCU in but not with it out why?

[Norcalgsx707]

My 95 gsx which i just got last night, was slipping lke crazy so I looked through these forums and seen somone suggesting to take out the TCU. I did and it seemz to run fine, problem is turbo goes to kick in and it takes the rpms down to like 2 it hesitates bad no check engine comes on like before I have no idea whatz going on can someone fill me in Im brand new to this car


I just wanna freak out I just gave up a good car for a car that started slipping about 30 mins after i drove it, Its a automatic Gsx it has had a transmission rebuild recently last night it was slipping then but for the most part would stay at around 400o rpms doing 55 I need to fix this thing so I have a drivable car ### help me..

also was giving code p0700

Seems like the transmission control unit (TCU) went out. P0700 is for the tcu.

looks like transmission fluid is pouring all over the place not alot but enough also so im f'd

make sure the cv joints are in and sealing..
just push and pop them in and make sure the mounting brackets on the joint is on there.

just out of curiosity,

what type of car did u give up for the dsm.
was it a trade?

 

[Norcalgsx707]

cv are hooked up to the transmission? btw where is the tcu at and how do i know if its bad

im realy like brand ne to these cars this is my first day owning one like i said it slips wont engage past 2nd engine ligt sometimes flickers on and it throughs a p0700 code when it does, pictures would be exceptional right now so maybe i can figure this car out

I gave up a 98 3000gt base sohc 212k on the engine this one only has 105

yes they're hooked up to the transmission.

and i once had a code for a bad tcu, and my car would shift right.
Idk why tho.

The CEL went away magicly and never showed up again.
Time of the month i guess.


doesnt sound bad.
Throw in a bit of work and you'll have a better outcome.

yeah mitsubishis are so senamental thats for sure mine wont shift past second and that light shouldnt come on and off

 

[93_tsi_fwd]

the tcu will be in the very back of the center console.

 

[Norcalgsx707]

how am i going to know its bad??
i also noticed this thiing dont like to go past 30 as soon as it hits 30 i slips

i have the tcu open and the ecu both look fine i

 

[Bud92gsx]

But if it's giving you a tcu code, chances are its bad..Try this to make sure the trans is fine.> http://www.dsmtuners.com/forums/articles-drivetrain/320324-homemade-shifter-automatic.html

The 2g wires are in there..If you can wire a sound system, you can make this.

How does this pertain to the op, or thread.A tcu is easy to bypass and make sure its not the tranny, it's the tcu.

 

[Norcalgsx707]

Does that hook up apply to the 95model exactly thanks for the help so fara transmission shop quoted 650 bench time and 1050 installed w/o transmission shops are rediculous

 

[Bud92gsx]

Yep in my previous post and the link says 2g wire numbers are in there...

I would be happy to save you 1000$,How about I save you 500$ and you paypal me 5...

 

[Norcalgsx707]

[Bud92gsx]

[Norcalgsx707]

just got to ask should i start replacing the sylanoids on the transmission and can someone send me a link to where they are located which one is which and maybe where I can buy them process of elimination is usually how I go

 

[Norcalgsx707]

So everything is fine with the transmission except 4th gear aka od? These cars are known to have weak end clutches and that is probably your problem. Easy fix.

this thing is being a true mitsubishi. its sentimental as hell had the IAC blow on me today ### it slipped when I put it into overdrive like always and reved hella hi, it goes to like 4 rpms then skips straight to redline hella fast it aslo blew a spark plug wire idk what the hell is going on but o/d is barley working slips 95% of the time sometimes it catches.

 

[Norcalgsx707]

I did a transmission fluid change and filter, and to my not so suprise the transmission fluid was brown with little tiny metal particles floating around also to make matters worse the idiot who put the tranny filter in the last time left the pan bolts on hand tight so it was also leaking.

so the tranny fluid change resulted in no slippage thang good but still cant engage those gears past 50 with o/d on any ideas??? I would like to fix this problem so I can drive this car right 50 mph just aint cuttin it
