A question of how much they are worth for sale.

 

Depends on what kind of transmission it is, what it's out of, and what condition it's in.

 

In good condition ..out of an 85 iroc z28. Think it might b a t5 . On the back of a 305 h.o

 

Probably a T-5.

Not many HO 305s that year; most were LG4. I'd be skeptical of the "HO" bit.

Kinda like people that offer to sell you [whatever whatever blah blah blah] off of whichever year Vette it was that had all those body rust problems... yeah this [fill in the blank] came out of one of those because they couldn't fix the rocker panels.... but when you run the casting numbers you find that it's REALLY out of a 75 Impala 2-bbl. Yeah right.

If it's REALLY out of a 85 Z28, most likely it's NOT a HO car. You can tell right away by the 5th gear ratio: a good car had .72:1 OD, but the LG4 had .63:1.

Apart from that, it's a 1st design T-5, with the straight roller bearings on the countergear, thrust washers as opposed to Torrington bearings, bushings on the intermediate gears as opposed to rollers, and brass blocker rings (what people who don't know what they're talking about call "synchros") as opposed to composition.

But more importantly, the front countergear bearing presses into the case, and has no seal other than the drive fit. The way the transmission fails TERMINALLY AND UNREPAIRABLY, is by the case stretching across the front, allowing the countergear and clutch gear to become too far apart. When that happens the fluid leaks out the front, which provides you with a GUARANTEED indicator of a wore-out worthless unrepairable transmission. Because not only does that show you that the trans is used up from the case being destroyed, but also, it usually fills up with metal chips from running dry, and all the noise and racket is what usually alerts the owner that it's time to sell.



When you look at it, look for the stain on the front bottom of the case, that the top half of this pic has. Which is, a 1st design T-5, with a stretched case, and the fluid leak, which is what made the stain. If it leaks fluid around that big bearing (looks kinda like an upside-down freeze plug) it is GARBAGE... toasted, and beyond repair.

In fact, in that pic you can even see that the bearing has been spinning in the case, which is what made that "band" of a witness mark you can see there, about 3/8" wide all the way around it.

 

It is 305 ho came out of my car. Tranny is awagner



On transmission<br/>

 

A 1st gen T-5 isn't worth much, everyone wants the 2nd design with all the improvements. I bought a later T-5 kit to swap my car for $800 or $900 a year & a half ago. That included flywheel, pedals, clutch, trans, console, shifter, ect ect. Pretty much everything needed to go from an auto car to a manual car.

If it is just the transmission I wouldn't pay more than $200 if it was in "good shape"

 

It is not a "Wagner", the mfr is Borg-Warner, as can be clearly read off the casting. The model is T-5.

What's the 8th digit of the car's VIN? (1 G 1 A P 8 7 ? x F N/L 1 xxxxx)
