Item Description
01-04 Mustang GT Mach 1 Tremec TR3650 5-Speed Manual Transmission Rebuilt 5134
5-speed manual transmission from a 2003 Ford Mustang Mach 1 with 33,130 miles. This is a Lashbrook Built transmission from 05/2022, but miles on the rebuild are unknown. This transmission was tested prior to removal and shifted through all gears properly and without issue. When drained the fluid was clean and free of any heavy metallic or foreign debris. There is some damage on one of the top bellhousing bolt holes, which has been detailed in the photos. A bolt still goes in and tightens, and all other bellhousing holes are in good undamaged condition. The input shaft splines are in good condition with very minimal wear. The factory shifter is installed and included, but does NOT include the upper shifter rod or knob. The pictures are of the actual transmission you will receive.
This transmission has been drained of all its fluids and WILL need refilled with the proper lubricants prior to use.
Fits 2001-2004 Ford Mustang GT (build date 2/22/01 and newer) and 2003-2004 Mustang Mach 1 with 4.6L V8 engine and 5-speed manual transmission as a direct replacement.

We accept all major credit and debit cards and the other payment methods shown at checkout, processed securely through Shopify. Payment is due in full at the time of purchase, and sales tax is applied where required.
For programmed ECU/ECM/PCM orders, be sure to submit your VIN, odometer reading, and current part number at checkout so we can program the unit before it ships.
We ship to all 50 states. Most orders leave our Hazelwood, MO shop within 1–2 business days by FedEx, UPS, or USPS, and you’ll get tracking by email as soon as it’s on the way.
Heavy items like engines, transmissions, and body panels may ship freight — we note that on the listing when it applies. Alaska and Hawaii have a flat-rate surcharge calculated at checkout. We don’t ship to PO Boxes or outside the U.S.
Local pickup is available at our Hazelwood facility by appointment — call ahead to set a time.
Returns are accepted within 60 days. A 20% restocking fee applies to standard returns, but it’s waived if we sent the wrong part, it arrived damaged, or it’s verified defective. Inspect your order on arrival and contact us within 7 days in those cases — we cover return shipping.
Programmed ECU/ECM/PCM modules are returnable only if defective, damaged, or incorrect. Because each one is programmed to the VIN you provide, we can’t take them back for compatibility issues from an incorrect VIN, odometer, or part number — double-check before you order.
Approved refunds are issued to your original payment method within 10 business days.
Every part carries a 60-day limited warranty against defects from the date it’s delivered. It covers manufacturing defects, parts that fail to function as described, and internal mechanical or electrical failure under normal use.
