I've brought in my car because I believe it is having transmission problems and I have a warranty. They have told me there is a code for the electronic pressure control system inside the transmission. However, they say there is now a vacuam leak on the intake engine manifold and until that is fixed they won't fix the transmission. I only have 2 mos. left on the warranty. Does this sound right to you and if so how much will it cost to repair the vacuam leak on the intake engine manifold?

did he read the OBD codes ? if not get them read as will indicate if a sensor/switch is causing the problem , good luck

Well your car is under warranty my friend, and if I were you i would go and raise hell at the dealer,try to read your Warranty book that came with your Car. -:)

Good luck

wow!!!!, this would drive me nuts,i would take it back to the dealer and tell them that i was told the problem was the module and they even made me buy theres, you paid them,they didnt diagnose the problem correctly,theres a problem with the abs,wiring or sensor or something, the point is you are having the exact same problem you paid for!! they need to repair this car even if they have to remove the module they put in that didnt repair it! talk to the owner this should not cost you anymore $,smiple they charged you and installed a part that did not fix the car,simple! if all fails file complaint with dmv and also advise them you will do so. good luck, let me know what happens, this is crazy the dealer cant fix there own make of car.

Sure it could . The ECU in these cars is eating up the gears. Been going on for a while.

Remove the transmission pan and you will see the solenoids. They can be replaced without removing the transmission.

I have a 2003 Acura TLS, bought new Oct 2002 currently with only 42600 KM (real low) My problem appears to be the same. I noticed specificly on warm days after 30 min driving, when coming to a stop, the idle was about 3500 RPM. Parked the car, turned it off. When starting up again, RPM stayed at 3200, also couldn't put into drive (possibly safety mechanism to prevent damage to transmission). After 30 min when cooled, was able to start again - OK.
I brought it to the dealer thinking possibly connected to FAULTY TRANSMISSION". There was a special extended warranty issued by ACURA >>> http://www.internetautoguide.com/auto-recalls/09-int/2003/acura/tl/index.html I believe it also includes 2002's. Your Dealer should check into it again.
My dealer, ACURA LAVAL (in Que, Canada) seemed to look at nothing else than the transmission. In fact, 2 days after not hearing from him, he told me that they had already ordered a NEW Transmission which is being put in as I write.

Hope this is helpful to any Owner/Dealer who reads this

it could b a loose connection at the computer

Code 0753 means Transmission 3-4 shift solenoid or transmission relay circuit problem. The PCM (engine computer) is seeing an incorrect input electrically for the gear or speed it should be seeing. You will need to find a qualified transmission shop to diagnose the problem. Possible causes for the trouble code start with worn/dirty fluid, electrical repairs & transmission overhaul.

if its just hesitating in that gear try adding some "Lucas brand transmission additive" to it. I've seen that stuff perform miracles

im a honda mech. if they had any sense they would call honda tech line and try to figure thi problem out i would replace thr trans again or have the connectors check if the tech lowered the trans with the wiring still connected he probably pulled some wires out of some of the connectors
