Common Problems with the 4T45E / 4T40E
The 4T40-E and 4T45-E are a transaxle series from GM and designed for transverse engine configurations. Since both transmissions used a similar design, owners can suffer from the same transmission problems including slipping, delayed shifts, harsh shifts, no reverse, no forward gears, loss of 4th gear, and the loss of overdrive. These issues can stem from numerous design flaws with the solenoids, a Torque Convertor Control (TCC) element, or other vital components.The 4Txx family replaced the Turbo-Hydramatic 125 transverse three speed automatic introduced in 1980.
One of the most common 4T45E / 4T40E transmission problems is overheating. This happens when the moving parts inside the transmission are creating more friction heat than the ATF can remove. The most common cause of this condition is towing heavy loads, driving in stop/go traffic, or on mountain roads where the transmission has to shift a lot.
You can also cause the transmission to overheat with improper maintenance or abuse. The main things you need to watch out for are overtowing and revving too much. These cause the transmission to rev too high and strip gears or use too much transmission fluid. The best thing to do, if you think the transmission is overheating, is to pull to the side of the road and let the vehicle cool down.
Updates to Remanufactured 4T45E / 4T40E Transmissions
- Fully remanufactured valve body, with updated TCC Control Valve, TCC Regulator Apply Valve, Torque Signal Regulator Valve, and Reverse Boost Valve, improves shifting, lubrication, and performance.
- Completely remanufactured pump, including replacement of slide pivot pin, provides consistent internal pressures, eliminates pump slide malfunction, and eliminates slipping and/or delayed engagement.
- Fully remanufactured torque converter is tested for leaks, lock-up, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibilities of front seal leaks, premature bushing wear, and vibration.
- Tru-Flat qualification process applied to transmission case, valve body, pump, and channel plate prevent cross leaks and pressure losses
- All-new custom-spec bushings to improve internal fluid flow control and pressures.
- Complete system correction and recalibration kit installed to address several OE flaws, reduce slippage and increase durability. Modifications include updates to servos, the PR system, and valve body accumulators.
How to Buy a Remanufactured 4T45E / 4T40E Transmission
1) Buying Locally
When you go to your local repair shop, they’ll order a remanufactured 4T45E / 4T40E transmission, then mark up the price. So at the end of the day, you’ll be paying 15% to 30% more than the actual cost of the unit.
2) Buying Online
Buying a reman transmission through a company like Street Smart Transmission will save you a considerable amount of money because you pay the wholesale price (avoiding a repair shop’s 15% to 30% markup), they’ll ship the unit to the shop of your choice free of charge, and returning your old transmission is free as well. Then all you have to pay for is the labor to install the unit (usually $400 to $800), and you’re on your way.
How Does it Work?
To order a remanufactured 4T45E / 4T40E transmission from a company like Street Smart Transmission, all you need to do is provide your vehicle’s VIN number, the mileage, and the address of the repair shop that you want it shipped to.
Financing
Replacing a transmission can be expensive, so Street Smart Transmission offers financing through PayPal Credit. Depending on your credit, you’ll be able to order a new transmission, get back on the road, then pay for it over time. You may have to pay labor charges for the installation up front, but you won’t have to shell out for the transmission all at once.
Shipping Charge/Location
When it comes to shipping, a transmission is quite heavy. So you’re going to pay quite a bit of money, unless the reman transmission company offers free shipping. Street Smart offers free shipping to a business address, which is usually the repair shop that you’ve chosen to install the unit.
What is a Core Charge (Core Deposit)?
Every remanufactured transmission originally came from somebody else’s car. Therefore, they need your broken transmission in order to refurbish it for another customer.
Your old/damaged transmission is called a “core”, and many companies will collect a core charge (usually $500 to $1500), which will be refunded once they receive your old transmission. (Street Smart does not charge an up-front core charge.) Make sure to ask any company for their core return policy, so you’ll know what to expect.
Our Recommendation
We recommend Street Smart Transmission. We have found Street Smart to be of the highest quality. Their transmissions carry a 3 year / unlimited miles warranty that covers both parts and labor. Their warranty is nationwide and attached to the VIN so it is transferable with ownership if you decide to sell the vehicle. It also covers both parts and labor for the installation of the replacement transmission.
