as i know trannies in our cars is the major concern,i came accross this article. it supporst the fact that "heat is the root of transmission failures"(aside from the fact of mfg defects) but i have read a lot of articles here and others , and this just makes sense along with other prcautions)3x3 change etc.)

let me now your opinions.

trans cooler will not solve the problem. removing the internal filter will not solve the problem.

enlarging the 3rd gear clutch pack lubrication channel WILL solve the problem.

 

Any auto car I come in to possession of gets a trans cooler as quickly as possible. Just a bit of preventative.

 

But in our case, it wont fix the problem or prolong its life.

 

Waste of time and money..... We know what the problem is and it is too little oil flow to the 3rd gear clutch pack. The fluid temps reach < 315F and this is what kills the transmission. You can read about it in the stickey transmission faq

 

Is there a driving style that causes more overheating of the transmission?

 

yes

lots of stop and go with heavy 2-3 shifting or just flat out hard on the car.

 

ive been threw it enough times nd ive told the tranyguys the same damn thing wich ofcourse they take offence to ,


have you heard of anyway for that to actualy be done and the capilaries widened?

 

If u have a cooler temps go down to 215 on a hot day in traffic. So a cooler makes a shit load difference. Especially cause when we have a trans warmer in our transmissions so it really helps balance out the temps. I have a cooler and I have a temp gauge which is insulated and in the trans fluid so it makes a big difference.

The real problem is putting a cooler on after the fact doesn't mean the transmission has not already suffered from too much heat... Therefore thecooler becomes a band aid. But if u get the trans rebuilt And have a cooler from the start u will be in a much much better scenario. Which I is what I did on the 2nd rebuild I have done. First one lasted 28000kms. Second one I am at arpx 80000kms already and it shifts like a beast. Mind u I do have upgrades clutches seals and whatever else is in their. But I can guarantee the cooler is a must.

 

this applies to automatic transmission only correct?

 

Yes, no such concerns for the MT

 

This. The Acura's transmission is not a heat issue. It's a design flaw. If someone was to make a shift kit it may resolve the issues but at this point no one has and very likely never will. With my old SHO they had lots of automatic transmission issues. Installing a simple $30 shift kit (couple springs and drill a couple holes) increased lubrication more than double than the factory standard and made the tranny pretty much bullet proof in addition to offering a white spring for neck snapping shifts at full throttle. Too bad there hasn't been anything like that for the CL.

 

This times infinity, all you are doing is cooling the oil that ISN'T getting to the 3rd gear clutch pack honestly.

 

So question .. I had my auto transmission rebuilt ~14k miles ago (at the 52k mark on my 2001 CL). The shop gave the typical 2 yr/24k mile warranty. I can already tell it's going to need a rebuild again, and will make sure this happens while under the warranty. Can I tell them to modify the tranny for this 3rd gear "more fluid" issue? Or are they going to look at me like I don't know what I'm talking about and ignore my request? And should I go ahead and add a transmission cooler while it's in the shop (maybe a gauge for shits & giggles too)?? If I'm going to keep this car another few years, or longer, I'd like a better guarantee the tranny is good and no more worries! I know these cars are good for hundreds of thousands of miles otherwise. Also have heard it's the quality of the Acura internals. Is there an aftermarket internal "kit" I should request as well?

 

Funny thing, My wife drove the car to work everyday for 7 years (Mainly, stop and go) and I drove the car most of time when we were together. I am a spirited driver. I pushed the Acura CL pretty hard on highways.

Transmission finally died 151K, we spent 3k to get it running. The car was in excellent shape.

Very odd how it worked out for us.
