700r4 (which one's to avoid)

I have a line on a cheapie ($100-150) but IIRC, there is a cutoff point, prior to which a person does not want to buy them. Does anyone know that year?

 

I just had one built and the guy at the tranny shop said that the 88-92 is the one to get. Before 88 they weren't as beefy and after 92 they have a computer.

 

Some of the later ones (there's no exact year cut-off) have a VSS plug instead of a mechanical speedometer drive. You can get the parts to switch it over from Bowtie Overdrives, but it'll set you back $70.

yup, 88 up are the best ones.........but if you are buying it as a builder, have the tranny shop build it up for what you want.

 

So, is there a number or code to I.D. the '88 thru '92 700R4?

 

If the I.D. sticker is still visible on the case, it's a four character code like 8GTR or 9CTF. Get that, and a GM parts counterman can decipher it.

 

very difficult to id it right --they changes some stuff in the tranny all 5 months till 84 - I have a 87 in my chevy but it was aut of "stronger" 5,7 camaro - so it was built stronger than the others and it is simular the 88 -- so I was told

 

Here is probably the best info on the Internet, Crosley is also a HAMBer as well as a tranny shop owner. He bailed me out on those trannies a few times including making a 700R4 work in place of a 4L60E in a 95 SS

If I remember correctly from an old magazine article, there is a visible difference between the good and bad periods...the earlies have several pressure test ports on the right side, later ones don't. Anyone here know iffen that's correct?

 

Thanks to all, the crosley page was the best, it shows that the lack of pressure taps ID's the case as 89 onwards. $70 for the electro-speedo change isn't too bad.

Who would you all recommend for a rebuild kit?

 

btod does seem to know it all don't they

And now they're selling their stage one for $850. Why rebuild?
