Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will be glad to help you with your Acura questions today.
Ok to start code p1740 is for a 4th clutch pressure switch failure. Normally I would say that you can replace the switch to correct this issue but with code P1750 being stored I don't think that will help.
P1750 is a Mechanical Problem in Hydraulic Control System of A/T Clutch Pressure Control Solenoid Valve Assemblies A and B, or Problem in Hydraulic Control System. This is usually due to an internal failure of the transmission that is obstructing the hydraulic flow through the valve body.
In short I would recommend replacing the transmission unless you can find a good reputable shop to re-build the transmission. These transmissions are very complex and have to be treated differently than most when doing a re-build. If the person that is re-building is not familiar with the product or uses the incorrect parts it can lead to another failure in the future.
I would also recommend having the work done at your local Acura dealer. The reason I say this is because they are very familiar with the vehicle and know what can and can't be done. They may even be able to re-build the transmission if they have a qualified person available.....this is the only route I would take for a re-build.
Also if you were to purchase a reman trans from Acura/Honda it would come with a 3/36K mile warranty which is covered at any Acura dealer in the country. The warranty on the existing transmissions is out now so I do not think you will be able to get any help on the repair, but you can always express your concern over this to the dealer and see if they can get some help for you.

To have an Acura reman transmission installed you will be looking in the $4000 range. To get the 3 yr 36K mile warranty that is where you will have to purchase and install the transmission. You can have one re-built for around $2-2500......you need to make sure it is re-built by a reputable shop or you will have problems in the future. You can also purchase a low mileage used transmission from various websites. I will link you to one that I have used in the past that we have good luck from. Here is the link:
You can also purchase a good reman from H and A transmission which is located in California. They provide very high quality transmissions but are almost as expensive as one from the dealer. Here is the link to their site.
Hope this helps you make your decision. Let me know if you have anymore questions and I will be glad to help. Please remember to leave positive feedback after the accept.
I didn't figure in the computer and the labor is very high. Our dealer would be around $1000 lower on the labor so between those two that is where the difference is. If the MDX computer is being replaced to change the shift points you should be able to pick one up from EBAY or from a salvage yard as long as the part #'s match up. From my experience with the Odyssey van the computer was recommended but not a "Have To" install item........meaning you can get by without installing the computer. That is for the Ody and the MDX may be different but I would not think that you have to install the computer. If this was quoted at an Acura dealer I would check with some Honda dealers in your area to see if they can beat that price. I know we have installed some transmissions in the MDX since it is close to the Pilot. Let me know what you find out.
