You’ve babied your car long enough and it’s time. You need a transmission.
Should you rebuild your transmission or install a remanufactured transmission?
There are three factors when it comes to this decision is time, money, and warranty.
A rebuilt transmission is going to probably cost less, but will take more time to complete. Your transmission is completely disassembled, cleaned, repaired and some parts are replaced. This takes roughly 3-5 days to complete. An Express Transmission Rebuilt Transmission comes with a 2 year/24,000 mile local warranty.
A remanufactured transmission will cost more upfront, however, can be installed sometimes that same day. A Certified Transmission Remanufactured Transmission also comes with a nationwide 3 year/100,000 mile warranty. Express Transmissions offers a complete range of remanufactured automotive transmissions for both domestic and international vehicles.
A Remanufactured Transmission that Performs Better Than New
To remanufacture is to make as close to new as possible, at our Certified Transmission factory. All wearable parts are automatically replaced. All core material is closely inspected and checked against original equipment specifications for correct dimensional tolerances. Replacement parts are new. Our Certified Transmission parts are made in the same production processes as original equipment. Testing is performed to manufacturer specifications and original production standards.
Production technicians thoroughly go through the core transmissions when they receive them. This can result in recommendations for upgrades to specific models. These quite often go above and beyond dealer specifications. Also, all known factory design deficiencies or weaknesses are corrected during the remanufacturing process.
Remanufacturing a Transmission Benefits include:
- You’ll know your cost upfront. There are no additional repairs or surprises because our Certified Transmission Remanufactured Transmission has already been through testing at our factory.
- Thoroughly disassembled and cleaned. Parts are remade specifically to factory-like conditions.
- Worn or damaged parts are replaced with OEM quality parts
- Any parts out of specification are machined back to OEM Specs
So Which is Better?
When trying to decide which is better for your situation, it’s important to remember, both options use a mix of new and old parts for your transmission.
While a rebuilt transmission may cost less up front, it will typically take longer than installing a remanufactured transmission.
If you are looking for a transmission for your vehicle, bring it to Express Transmissions. We will evaluate your transmission and offer suggestions for remanufactured and rebuild services to make your transmission feel like new.
Remanufactured Transmission Spotlight
Although similar in design, the Ford 4R70W/E and 4R75W/E transmissions differ in that the 4R75 offers significant improvements and revisions that include a revised fluid pump, a ring gear that has been strengthened, and torque converter that is stronger as well.
Introduced for the 2003 model year to be a more durable alternative to the 4R70, the 4R75 is a lighter duty transmission that is commonly found in 4.6L V8 engines and the larger V-8 with a 5.4L beginning in 2004 used the 4R75 transmission exclusively.
With the exception of the electronic speed sensor that is found on the later of the two units, the 4R75W and the 4R75E transmissions are identical in design.
Like many considerations of the 4R75W/E and 4R70W/E transmissions, the ratios are identical to one another’s. Both the 4R75W/E and the 4R75W/E were offered at the same time throughout the time period of 2003 to 2005, the 4R70E ceased being offered in U.S. applications at the completion of the 2005 model year. The 4R75E was offered through the 2008 model year but did not make a return in 2009 with the 6R80 taking its place in Ford’s F-150 lineup.
The “E” models of the transmission utilize smarter shift schedule that resulted from a greater integration between the engine’s PCM and its transmissions sensors.
The 4L80E transmission evolved from the heavy-duty TH400 transmission. The 4L80E offers 4th gear overdrive feature whereas the TH400 only offered a total of 3 forward speeds. It was the need for an overdrive transmission that was the ultimate reasoning behind retiring the TH400 transmission.
Having identical ratios, the exception of the 4L80 was that it has a 0.75:1 overdrive used for 3/4 and 1-ton pickup trucks that have either a 6.2L or 6.5L diesel engine.
The 4L85E offers an input torque capacity that is slightly higher and used with GMC / Chevrolet vans (up to 2005 model year) with the Duramax diesel engine. Thereafter, the 6 speed 6L90 replaced the 4L85E.
The 4L60 was used in lieu of the 4L80 during the same time period for half-ton 6.2L/6.5L diesel. Used by GM gasoline engines until 2009, the 4L80E transmission is electronically controlled. When the Duramax diesel was first introduced for the 2001 model year, the 4L80E was replaced by the Allison 1000 as it was not capable of holding up to the engine’s rated torque.
