im thinking about changing my stock VX tranny out for a DX, maybe even an EX/SI, my questions are; what is the # on the ex/si tranny, and the part # of the DX tranny. i was also wondering if i would need to change anything keep the speedo accurate <--- main question. thanks in advance.

 

bump please help

 

What's the year of the tranny/car?
And as far as I know you dont have to do anything to keep the speedometer accurate. That's what a VSS is for.

 

its a 92vx, im not sure on the tranny yet, what do yall recommend???

 

is the S20 tranny the SI/EX, and the B200 the DX, and the A200 the cx/vx?? if so thats all i need to know. if not im lost.

 

K simple i would suggest at least getting an ex/si motor but if yuo don' t have money for that at least get an ex/si tranny shortest guears and no you just bolt on the tranny and you are good to go

 

dont worry about another motor. they arent that much more potent unless you stray from the d series or go with boost.

anyway for some real sustanence in this thread:

mista bone is my d series hero - http://home.cinci.rr.com/mistab0ne/tranny.html

as you can see, any transmission is better than the vx tranny. however you will lose some mpg. i say if cost is a concern just get the dx tranny. ex/si trannys usually cost more and you will lose an extra mpg with it.

the difference in ratios from the cx/vx tranny to the dx is MUCH greater that the difference from the dx to the ex/si.

bottom line - pick up a dx thats in good condition

 

ok, i found the mista bones site after the post, but im still trying to figure out how to tell the differance between the DX tranny and the CX/VX, they both are small bearing cases and both are A000 right??? how to tell??

 

you have to pull them appart. or make sure you know what car it came from

 

it will bolt right up. and yes i would get the S20 out of the EX/Si. If you cant afford the full D16Z6 swap, do yourself a favor and switch out the VX intake manifold for the Z6/Y8 as it will flow better.

 

i plan on swapping in the z6, but need to find some writeups of swapping into a VX, anybody know of any links.

 

.

 

you don't need a wirteup....verry straightforward.....pull off all connections, remove motor, re install new motor reconnect everything, wire up the O2 sensor (VX uses a wideband) and your done.

 

so the motor/tranny ecu is all plug and play with the exeption of the 5wire to 4 wire o2 conversion?? if so then thats not a problem.

Yes.

I swapped out my vx trans for a dx trans, its alot better than the wider gears in a vx but honestly you best bet is to find a z6 or y8 trans.

 

cool, you guys are awesome, i guess i know where to get my info from now on, thanks alot. Lee.
