Acura Integra Transmission Problems
I have a '90 Integra 1.8L LS hatchback with an automatic transmission that does not want to shift from 2nd to 3rd. At least not until it warms up. Let me regress a bit... I bought this car for my son 2 years ago and everything was fine for about the 1st year. Then, it seemed to take longer to want to shift and it has progressively gotten worse. At first, it was slight, then noticeable, and now it is up to about a 10 minute drive @ 3000 - 4000 RPMs. Once it makes the shift, all shifting is normal except for a slight slippage going from 2-3 and that quickly goes away and easily controlled with the throttle. I have drained and refilled the tran twice thinking that it helped each time for a short while... but to be honest... it might have just been hopeful wishing as it has never gone away.
Can any of you extremely knowledgeable people out there shed any light on what the problem might be and any corrective action I should take? Is this transmission just shot.. if so... any suggestions (other than the tax write-off for donations)?
I know engines very well but trans are not my area of expertise... but neither was engine rebuilds/overhaul/swaps... until I just dove into it... more than a few times on more than a few vehicles.
) I honestly have not had the time to do any checks (like pulling the solenoids and cleaning/checking them) so I would like to find out a logical way to troubleshoot this problem. I have full schematics but I do not know how the shift control is done... I do know there is a 'tran control module' but have no idea as to what should happen when and what for. I have full test equipment (MM, O-scope, etc.) but want to know where to start. Thank you in advance for any insight anybody can give. All comments are welcome and grateful!

I dont have more time to spend on my computer... thanks...
My email add is endoescudo@yahoo.com
Thanks again...
I have the same exact car with the same exact problem - I have been warming the car up with the Ebrake on in Drive so i can drive the car to and from work. It is not an internal problem - there is a shift solenoid that is not working. I need to do some more research, but i think this is an electrical issue - not mechanical
Last time my mechanic told me that he'll use an AT Fluid that he uses on his off road cars... I dont know about that, but with what he told me it might have a faster heating process, the good thing was, he was honest to tell me that he wasn't sure... Ill keep you posted.. thank you so much...
Using there ATF did not made any differnce though my mechanic said to change my tranny.... I dont want to.. well not yet until i have everything checked out...
My problem has become worse now... My tranny DOES NoT SHIFT now, well that was after a had my engine changed oil and changed my spark plugg. :sick: I really dont know what to do next... Any updates??? id really love to hear it.... thnaks...
Well I ended up doing a tranny swap a few weeks ago from another teg and it works fine minus the cost to do it. But love my ride none to less. I have read on other boards about this problem and wonder about it maybe over 10 other peeps I chatted to and no real answers give some feed back if you find something. :confuse:
Same problem occur on my 1990 same model as yours.
Cost of new switch in 2005 was $60 Can
Part number I have for it is 35700-SK7-A01 Swtich Assembly
Hope this helps.
The problem will get worse as time goes too the point that you will also be not able remove your key from the igination because the shifter will not indicate when you are in park. :mad:
The age of the vehicle could have resulted in it stretching or corrision inside
Thing that was done...
1. Had it checked to another mechanic... Found out out my Bulb Body stacked-up so i had my tranny removed and checked.. things where going well unil it was installed again... Worse... at first it shifted really or then after a couple of minutes a cracking sound then a sudden stop no movement at all.. the next day tranny was checked then found out the plates where abraded...
2. So, removed the tranny again and changed the plates... after installation and trial ride... no movement at all... no shifting happend... :mad: :confuse: :sick:
3. We contacted a Automatic Transmission speciallist from another city had him fly to where i am.... after he checked on it mechanical point of view where all ok that is after he started the engine... just that it doesn't shift.... Solinoid was checked and it is not functioning....
4. Its been 2 months no I till cant find any solenoid
I went to SUZUKI dealer it may take another 2 months b4 it can be delivered.... but the problem is not that its the PRICE: about $375 just for the solenoid... thats too much...
for me and even the speciallist said it is to much....
HELP........ Do you know wher i can get a cheap solinoid? 1990 model 3 doors suzuki escudo... HELP
My thoughts: change my tranny and engine... for one reason nobody here is selling tranny only... it costs about 40,000 pesos that is about $870
: Change my tranmission to manual--- Problem can find any, for my car here in my place
Thanks guys

Iv seen this on Chysler mini-vans, and GM cars so it just seems that maybe iv over-looked this.But i will repost as soon as I try this.And from looking on more of these threads, alot of Acura owners could use some info on just this same issue!
Made a vibration/whine going into 3rd leaving home. Stopped, backed up reverse OK, then 1st started whinning and running like not in gear. Got home, maybe a 1/4 mile. Is this the clutch and guts gone or a tranny out of time?
When I moved to NJ, I drove my car non stop from FL to NJ for 15 hrs.
I love my car as it never let me down, I drove entire FL and even to key west at 90 mph and I used to enjoy a lot.
The first day of NJ when I was driving at 25mph I met with a small accident as I do not know that NJ is full of traffic and people can stop anywhere on road. I had to replace my left head light and airbags for $1500 and checked my dashboard wires.There was a minor scratch on my front bumper.
now, my car was not running as before and it used to shake when it reached 80mph and rpm used to shoot between 2k to 6k frequently and when contacted the mechanic, he replaced transmission fluid and asked me to warm my car before driving and I used to do the same.
But, no Change, rpm was frequently fluctuating and there was delay in gear shift
For NJ DMV inspection,I had replaced gas filter, distributor, val cover gasket, new spark plug,NGK igni wire set, for $1000 and also replaced transmission fluid
same problem with rpm and it was more consistent
one day there as a lot of noise from dashboard as if some wire was struck between odometer and the next day onwards there was no noise.
last week my car broke and I towed it to mechanic and he replaced thermostat, gasket, new heater hose and the mechanic said its due to Anti freeze liquid leakage
the next day when I drove my car, it wobbled and vibrated a lot while driving and there was delay in gear shift from 2nd to 3rd and I immediately slowed my car
but, suddenly it broke on main road and did not start, even if it started it used to stop and after 15 min it started.
But I don’t want to take chances and towed it to Mechanic and he did Check Engine diagnostics and said its a Transmission problem and advised me to sell my car.
Now, it has 105k miles on it. When I came to NJ it was exactly 100k
I don’t know what to do,
I have three options
1. Sell my car? KBB fair value is 3600, for how much I can sell?
2. Show it to Acura Dealer and fix Transmission it. If so, how much I can spend
3. Continue as it is?
The dipstick is sucked down its retaining hole and there is one hell of a vaccum holding it in place. The only part visible is the ring at top. I called my mechanic who said dont pull it out. I need a new used tranny. I have a yearning to somehow get it out of there. Any advice or prior experience with this.
but the 94-01 trannys are hydralice and the 90-93 trannys are cable so you would have to convert it
PS. the 92-93 GSRs are VERY RARE so take care of it and lock it up because the motor is a one of a kind
the tranny will shift from 1st to 2nd fine when cold but will not go into 3rd until warmed up, after it is warmed up the tranny shifts into all gears fine.
Can any body help me with this problem?
first of all i started to feel my cluth slipping, new cluth would be no biggy.
but it eventually started to get harder and harder to get it into gear. When i do get it into gear its very inconsistant(shakes, grinds chugs w/e)
Now its worse than ever! about half the time i just cannot get my car into gear. I have to shut my car off and then it will go in no prob.
o yeah! and sometimes when i have it in gear i cant get it out and it just keeps moving.
i am freaking out! someone shed some light on my prob please.
I perform this service first thing when these issues arise and in many cases eliminate the problem. this may be other than the owner who is constantly racing the vehcle.
Please help if you can
I only paid $250.00 for the car and now have over $1500.00 in it with new axsels and all new brakes and stereo and all the parts i have put in for no reson i guess

http://www.youtube.com/watch?v=FfjGohWy-OU how it works
I have the same problem, I have it in gear and no movement.... but im going to start with the cheapest thing... adjusting the cable. then fluids, then well... if ima get a new tranny, gonna get a new clutch. Thats my opinion.
