#1 of 53 Automatic Transmission Problems by go8b

Nov 02, 2006 (7:44 pm)

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. :o) 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!

go8b - DONT SWAP your tranny
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

Yes, there are two shift solenoids on the transmission. They are mounted on topside with electrical connectors going to them. I have tested these solenoids and both are working fine. I also did continuity check of all wire feeding them and all was ok. I believe the problem to be with sludge and junk build-up in some ports that cause too much positive pressure to shift until it heats up enough to melt. I have had no time to check into it any further but know that a standard tranny flush may or may not temporarily help but will not fix the ultimate problem. THANX FOR THE REPLY tho... and keep me posted if you resolve anything.

Thank you so much for your reply... Im gonna go to my mechanic to check on what you said...
 
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...

I own a 94 Teg LS and had the same problem and everytime I went to do mods on my ridge most told me that it be better to wait till it gave out.I hoped it would hold out a bit longer but it did go out and would not shift.I thought it was the solinoids but checked them out and it was internal. Sad I pretty much baby my ride and have everything on it tuned up.
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.

May want to check what is called the shifter switch located on you shifter column. You will need to remove your centre console to see it.
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.

If the switch is okay then the next item to check is the shifter cable.
The age of the vehicle could have resulted in it stretching or corrision inside
