New guy with trans questions
Hello all, I'm new here. I hope I'm in the correct place for this question, and that's it's not too technical. This has been haunting me for a while. I tried to get some answers, but other sites were trying to get a credit card # from and suck some money out me before answering, and thought I'd run it by you guys first. Thanks in advance for reading and any help or directions that you might be able to provide. Here's the question:
What should the engine RPM's be on a 1999 Acura CL with a 4 speed auto trans at 70 MPH. I'm currently getting about 2500 RPM"s at 70 MPH while cruising on the interstates. Is this right?" The trans seems to shift ok on acceleration but seems to be somewhat confused on deceleration as to what gear it should drop to or be in. It almost seems more like its slowing down like a manual trans rather than an automatic. Otherwise the car runs and shifts fine. I have millions of miles of car driving experience, and deceleration for this automatic trans seems odd. Car has about 86,000 miles and is very reliable. We often do 6 hour 300 mile trips with it without any trouble, but the trans just seems odd when slowing down. It seems more like an electronic modulation issue with down shifting because it certainly shifts smooth when accelerating and cruises okay, but I'm just not sure if the RPM's are a little high and if it's dropping back into lower gears properly. Wondering if this could be normal on this car? My wife drives this on long trips and I'm a little worried. Any help would be greatly appreciated. |

Re: New guy with trans questions
That is exactly how my 1999 Accord behaves. I think this is normal.
On the side note, at this age and mileage I would do ATF drain/refill (if not already done). Sam

Re: New guy with trans questions
I cannot tell you for sure - my daughter is driving it now, but if I remember correctly it is something below 3000 rpm. At the beginning of the month I will visit my daughter. If I get a chance to driving a car, I will take a look at it.
