Product Description


New 5th Gear Mainshaft 34 Teeth for 2001-2010 Ford Mustang 4.6L TR-3650 5 Speed Transmission.  5th Gear Found in 1st Design TR-3650 5 Speed in 2001. It was then not used the next 3 years, but, reappeared in the 2005-2010 Ford Mustang 4.6L TR-3650 5 Speed.  This 5th Mainshaft Gear runs/mates with a 61 Tooth Countershaft Drive Gear (Part# TCKT1887).  However, the 61 Tooth Cluster 5th Drive Gear is very hard to Acquire.  Usually we only get these if we separate a Core that is exchanged to us on a Reman Unit where the Core isn't worth rebuilding due to expense.  Feel free to email our Sales Department, sales@astroperformance.com , for any Good Used parts needs that are not marketed on our website.


This gear is shipped with Freight already included in Price of Component for anyone in the Continental U.S.  Freight Charge Included is for USPS Priority Mail. Usually a 2-3 Day Service once shipped.  Average handling time to ship this product out is 2 Business Days from date of purchase.

Expedited Freight is available. But, at an additional charge. Anyone wanting Expedited Freight need to consider & do the following:

-Expedited Freight is available on "Stocked Items" only.  Please note that just because the website says the product is available, it doesn't mean 100% it is.  This is due to the amount of gearbox builds we perform with multiple builders constantly pulling components from shelf and the gearbox components for that build not necessarily being billed out in a timely manner.  It is always a Great Idea to email sales@astroperformance.com to check Availability before purchase.

-Expedited Freight is performed thru Fedex Express Air, USPS Express Air, and UPS Air Services.  USPS Express & UPS Air Services are picked up from our warehouse Monday thru Friday at 4:00pm EST. Fedex Express Air is picked up at 4:15pm EST.  Regardless of what Service end user picks, it is important to get either an email in to our sales department requesting freight quote before 2:00pm EST for shipment the same day. Please email sales@astroperformance.com for Availability and Expedited Freight Charges.

-Both Expedited Freight Charges & International Freight Charges are Quoted and Billed out separately from the charge of Product Purchased on Website. Astro Performance Warehouse will send a "Request for Payment" thru Paypal to Email Address that the Quote & Availability Question is sent from. CUSTOMER MUST PAY ADDITIONAL FREIGHT CHARGE BEFORE PRODUCT IS SHIPPED!
