So, I just bought a T-5 trans, clutch/brake pedals and slave setup from a 84/85 Z28 HO in a boneyard for a real good price to swap into my 92 Heritage edition. I get it home and start investigating finding a manual for this thing and it asks for the number. 1352-071. Comes up as a 85 2.8L v6 camaro/firebird transmission. Clearly I know this isnt right because the motor was still in the car and it was a real V8 HO motor. So help me out...is there something I dont know? 1352-072 is supposed to be the V8 number but this came from a V8 car. Does this screw my swap? I took the number from a green sticker on the cover NOT the suggested metal tag as its unreadable.

Also. Oreilly auto lists different flywheels for the 85 and the 92 both 5.0s Is this difference caused by the intro of WC T-5s? I don't know which to use if I can even use the transmission.

Thanks for any help anyone can offer. Got to get it on the road!

 

Can't say about "tags"; I don't find those to be particularly useful.

For example, someone could have got a case from somewhere with a "tag" that says it's one kind of transmission, and put some COMPLETE other guts in it. Not common, but not impossible either. Therefore the "tag" is NOT absolutely foolproof (let alone sofakingdom proof) identification.

However, THE PARTS don't lie. Can't. They tell the TRUTH about what a thing is, EVERY TIME.

Look at the splines on the clutch gear. If there's 26, it's a V8 trans. If there's 14, it's a 6-cyl one.

As to the flywheels, the V8 engine changed from 2-pc rear main seal, to 1-pc, in 86. Therefore 85-back uses one flywheel, 86-up uses a different one.

Furthermore, in each year bracket, there are 2 flywheels, which differ in weight. The 16-lb version was used in high-perf setups like the L69. The 22-lb version was used in the grocery-cart ones such as the LG4 and L03.

You'll have to use the year variant that fits your particular motor; but the weight is a personal choice.

"WC" :barf: uke: :gag: doesn't make any difference. In spite of the fact that some unfortunate department's inexperienced summer engineering intern gave the 2nd design of that transmission the PIT Team Total Quality Six Sigma BUZZWORD name probably as a joke to see if anybody was actually even looking at ECNs before they signed them (see "ignition switch recall" for a similar scenario), the external dimensions of the transmission did not change even though there were several internal changes.
