D Series Transmissions Questions

Howdy,

I have been searching for a clearish answer on this, but was not able to find it, so i have probably just looked right past it. So i do apologize up front since this is probably asked alot.

I have a D15B7 mated to a CX manual transmission.
I am seeing if anyone has changed to either a DX or a SI transmission and noticed that first gear uphill is easier.

Thanks for any advice. I have looked at the gear ratios, and i was not clear if all of the DX/LX/SI/VX/CX transmissions appeared to have the same ratio for first gear, is that correct?

Additionally, this is just my daily driver that hopes to become my Project Car in a year or two.

Yes, the DX would pull uphill easier and the Si easier still. Don't overlook the final gear ratio. It affects all gears.

My first coupe had a VX transmission in it when i first got it. it SUCKED.

you will never look back when switching to a DX or EX/Si. go for the 2nd if you can. but a DX is still a huge upgrade.

Thanks for all of the information.
I'm leaning towards a SI/EX Transmission. Much appreciated. Would have done more search-fu, but I am in the middle of moving.
