Name this part on an SR20

[heated heavy]

Can anyone tell me what this part is and its purpose. Its located on the tranny. Im installing an SR20 into a datsun and im seeing if i can get away with taking this thing off for its getting in the way.
thanks alot!

Speed sensor. There should be one 10mm bolt bolting it to the trans.

thanks. i new it was a sensor of some sort. are there other alternatives to reading the speed? just in case, is their any tranny oil thats gonna spill out if i take it off?

[HIGHMILEHATCH]

I'm not aware of any other way to read speed.

Yes, I believe trans fluid will come out.

[psycko069]

no there is no other way to read speed. yes tranny fluid will come out if you take it out..................

get s15 trans and rear end.
S15s have the speed sensor in the rear end plus you get the 6speed goodness.
Bad news: They are not cheap.

Don't make things more difficult they need to be.
Plenty of SRs have been put into dimes with no problems whatsoever.

its a datsun 1600. engine bay is much smaller than a 510. which also means the bulky 6-speed wont fit in the transmission tunnel. oh well, back to cuttin'.

try fitting an SR bellhousing on a CA18ET/CA20E s12 200sx box. If you can, get an 1986-88 transmission (stronger than the 84-85 ones). Its a much smaller tranny, but it'll take s13 bellhousings. I run a KA24 in my s12, and all that I did was swap the s13 bellhousing onto the smaller CA20E tranny. It also uses a mechanical/cable speed sensor that is smaller than the electronic one that s13's use.

oh you're putting it into a roadster? nice.
I've seen a few SR20DEs go into those.
