Sorry, we're temporarily sold out.

We take great pride in our Syncro transaxles, and we cut no corners: All four synchro-rings are the latest OE moly-coated type, all six OEM quality bearings, all new gaskets, all new seals, completely rebuilt "cross country " low-range section—and everything is set up properly with the correct tools. We have also updated the problematic original 3-4 synchro-hub to the later style that won't break (no more threat of sudden death syndrome), and all our transaxles get a NEW 4th gear. That's right, the Vanagon transaxle is going the way of the Bus: They are all getting old enough where a new 4th gear is essential. There is simply no way to measure the engagement teeth on a gear to determine without any doubt that it will work properly, or for how long. It is a judgment call. Subsequently, the most common warranty issue is: "It pops out of 4th gear." No more! Every GoWesty transaxle gets a NEW 4th gear! In addition, each and every manual transaxle we build comes standard with our lubrication enhancing "splash plates" kit for unparalleled longevity.

GoWesty transaxles are rebuilt, not new. New transaxles have not been available for many years. The price listed is exchange, and a core deposit will be added at time of purchase. There are many parts in your old transaxle that cannot be purchased new, and are very valuable. So we need yours in return. If you do not return it, you forfeit the entire core deposit.

NOTE: We offer two ring & pinion options: 1) Good used 4.86 ring & pinion at no extra cost, and 2) brand-new 4.86 ring & pinion for an additional $1300. If you choose the brand-new ring & pinion option, you are guaranteed $1000 of your core refund, regardless of the condition of the ring & pinion in your core return—we encourage you to choose the brand-new option!

Available gear carriers:
• Rebuilt magnesium gear carrier 
• Brand-new OEM aluminum gear carrier (additional $330). When you purchase this upgrade, you are guaranteed a full core refund on your returned gear carrier, regardless of its condition. 

All GoWesty manual transaxles are shipped without oil. Per our warranty, Red Line GL5-75W90 gear oil. Available separately below.

CUSTOM GEARING: The transaxle described above is geared the same as the original transaxle. The final drive, and all individual gears are the same ratios as what came standard in all vehicles sold in the USA. Custom gearing is also available. If interested, email for a custom quote.

Want to add a Peloquin ATB or "locking" ATB differential to your non-locking transaxle? Now you can do just that. Choose your option in the drop down menu, and for an additional $1300 - $2100, we will send you a transaxle with a Peloquin™ Automatic Torque Biasing Differential installed.

The simplest and lowest cost option is the standard fully automatic unit (GVW-POSI-M) that requires no driver input or vacuum system to operate, and while it greatly improves traction on and off-road, it does not fully "lock" the differential. If you desire the maximum available traction for all environments, the GVW-POSI-L includes not only the posi-traction device, but also integrates a fully locking function. This option requires additional internal locker parts, and an external vacuum servo and bracket that are included in the cost. *Note: If your Syncro did not come from the factory with the vacuum locker actuation system, you will need this additional kit to operate this modified transaxle.

WARRANTY: Warranty coverage is 48 months/ 48,000 miles (whichever comes first) at no extra charge. You are required to use Red Line GL4-75W90 gear oil. Please note that the warranty on this item is VOID unless a decoupler is installed at the same time as the transaxle. Please click here and read why. GoWesty rebuilt transaxles DO NOT include the front drive shaft power-take-off section, which is where the decoupler fits, available separately. The one removed from your old transaxle needs to be transferred over if you decide not to install a decoupler (which is a mistake!). Our "Easy Rider" and "Road Warrior" policies can be purchased separately to obtain greater coverage. Click here for complete warranty details.

CANCELLATION POLICY: We put a lot of time and energy into packaging your GoWesty rebuilt transaxle. If you purchase a transmission from us—and then decide to cancel the order within 30 days—we will refund you in full, minus any transportation fees and a 5% restocking fee. If you decide to cancel your order after 30 days, our normal return policy applies (view by clicking here).

SHIPPING: This transaxle ships via TRUCK FREIGHT due to size and weight. Initial shipping costs for this item are subject to change as the order is processed. Shipping cost include the price or returning the core to GoWesty. Please contact GoWesty to arrange return shipping of your core.

$1800 CORE CHARGE: A core charge is a deposit until your old transaxle is returned and inspected. All or some of this deposit may be forfeited depending upon the condition of the core. To view our core check out sheet, click here. NOTE: If you choose the brand-new R&P option, you are guaranteed at least $1000 of your core charge refunded, regardless of the condition of your used ring & pinion. 

$250 CRATE CORE CHARGE: Your GoWesty tranny will come in a very nice shipping crate. We MUST get this crate back from you; hence, the crate core charge. This deposit will be refunded when you return your tranny core in the crate.
