I'm toying with the idea of removing my TH350 and putting 700 R4 in place of it. I really like the the standard gear ratios and the fact it's a 4 speed.

Im planning on having the transmission strengthened in the necessary areas to handle extra power. Question is, will it bolt directly to my ZZ4 and be a direct swap for the TH350? If not, what will need to be modified or changed?

Thanks

It will bolt straight to the block, but you will need a slightly shorter propshaft (about £200 from Bailey Morris) and you'll need to move the stock cross member back by redrilling the holes in the subframe.

Sounds pretty straight forward then No need to widen the transmission tunnel then?

No, it's tight, but it'll fit straight in. Some pics on the last 3 or 4 pages of my build thread I think

Thanks Any particular reason(s) you opted for such a transmission? What did you use beforehand?

My car originally had a TH350, then I changed the rear axle to a 4.11 and needed the over drive.

But with my engine making a reasonable amount of power I built the box with a few upgrades to make it reliable. There's a few things to be wary of with the 700r4, but it's a simple transmission.

If you want your transmission checking over, or modifying, let me know

I've have heard the 700r4 is a weaker than the TH350 and TH400. That does worry me a little bit, but yours has been strengthed to cope with extra power? How much lbs ft are you putting through the 700r4 and what sort of usage does it see?
