Transmission Options
Tremec TKO / TKX
T56 / TR6060
T56 - Way too expensive. $2000 before you can even get your hands on one.
AR5
There are two main Aisin AR5 transmissions that can be used
- Car (Spindle) Version
- Pontiac Solstice 2006-2010
- Saturn Sky 2006-2010
- Truck (Yoke) Version
- Chevy Colorado 2004-2012
- GMC Canyon 2004-2012 https://www.fabbotfab.com/products/fabbot-ar5-to-ls-nexgen-adapter-bundle?variant=42035111657718
A lot of canyons and colorados can be found in the UPull&Pay Junkyard. It's not clear how many of them are potentially manual transmissions...
| Part | Vendor | Cost |
|---|---|---|
| AR5 Transmission | eBay | ~$1000 |
| UPullIt | ~$180 |
FABbot Kit Costs
The all in one kit costs $1459.06. It includes
- 3x Redline MT-90 Transmission fluid
- LS1 Flywheel
- Cyber Clutch
- 4L60E Bell housing and hardware
- Spacer for slave cylinder
- 36" Feed line
- Slave cylinder with -3 fittings
Piecing it together instead yields
| Part | Vendor | Cost |
|---|---|---|
| 4L80E Bellhousing | UPullIt | $50.00 |
| GForce Performance Adapter Plate | GForce | $279.20 |
| T56 - LS1 Clutch Kit | RockAuto | ~$200.00 |
| Slave Cylinder | RockAuto | ~$50 |
| Flywheel | RockAuto | ~$75 |
| Clutch Hydraulic Line | RockAuto | ~$63.89 |
| Clutch Alignment Tool | RockAuto | ~$1.55 |
| Transmission Fluid (3x) | RockAuto | ~$20 |
| Grand Total | $741.00 | |
| Yeah that's $700 in savings right there. Sounds good to me. |
Will likely need a new master cylinder too. Rock Auto has one for ~$30 bucks.
It looks like if I can find a used one in the junkyard I can have a complete transmission assembly for close to $1000.
Mounting
I think I may have a mounting solution. I'll just have to modify my current transmission mount. Cut the barbells off, and then just fucking send it. There's also this one: https://apexengineered.com/shop/z31-300zx/transmission-mount/
Z32 Transmission?
Take a serious long look at this. There is big potential here. Pros: transmission mounting would be easier, driveshaft likely easier Cons: transmission is rare, not necessarily easy to get. Too Expensive
