ls1 trans

[chilecaprice]

Hey Guys,

Im new to here but not new to building cars. My GF and I are starting a project for her. A 1970 Nova with an ls1, my question is I dont want to go with an elctronic trans kinda like the idea of a turbo 350. Is there any way these 2 can bolt up.

Thanx for the help,.:rolleyes:

yeah you just have to leave the top bolt out i think. I know it's one of them the rest will line up fine

You're going to be giving up alot by going back to a th350. The 4l60e/4l65e's are more efficient, better first gear, and the o.d....two piece case design is alot stronger than the old th350 housing as well.

I know the good and bad of the 4l60e, but Im thinking more along the lines of the wiring that is involved. I saw that painless makes a wiring harness for the ls1 but dont know if if can control the trans if so ill take it. If not just seeing what options I got.

The stock harness can be reworked very easily since the delphi computer that runs the engine also runs the trans, it's pretty straight forward.
If you want someone to do that for you, my friend bought a Howell FI harness, they did a nice job, I'm pretty sure they're the ones who build harness's for Turn Key.
I've seen lots of auctions on ebay to rework harness's as well.
I'm doing a 5.3/4l65e install in my rockcrawler rig, plan to do the harness myself using the original and just thinning it down, I had the computer reflashed for less than $100 so that it would match my configuration/needs.

Another idea would be to use a th700. I should say a 700r4. I had one behind a bb and was quite pleased.
