Prepare the 4L30-E Transmission In Your BMW 328i For Road Racing

Posted by on Thursday, January 30th, 2014

The 4L30-E is a four-speed automatic transmission designed and built by General Motors. It was put into production to replace the 3L30, and was eventually replaced with the 5L40-E.  The 4L30-E was designed for rear wheel drive cars. It was first used in 1984 and was eventually phased out of the lineup at the end of the 2003 model year. It was used in the Cadillac Catera and the Chevrolet Omega. It was also used in other brands and models outside of the General motors lineup, including the Honda Passport, the Isuzu Amigo, the Axiom, the VehiCROSS , the Rodeo and the Trooper. It was also used in a number of BMW vehicles, including the very popular and sporty 328i.

The 328i is a fairly small car, available as a two door coupe or a four door sedan. They are also pretty lightweight. As these cars age and become more affordable on the used car market, many of them are being modified for road course racing. Racing of any type can put a lot of additional stress on a car, especially the automatic transmission. Let’s take a look at a couple of things you can do to better prepare your 4L30-E transmission for road racing.

The first thing you should do is install a shift kit. A shift kit will offer a number of benefits when racing. First, they will include modifications that raise the transmission’s line pressure. This will provide for more clamping force on the clutch packs and aid in preventing them from slipping. Second, a shift kit will help reduce the time it takes for the clutches to fully apply, reducing both excessive heat and wear. Finally, a shift kit will offer you more manual control of your automatic transmission. It will also allow you to hold the transmission in a signal gear longer before it shifts, as well as give you the ability to downshift at higher speeds.

The second thing I would recommend you do is upgrade your organic oil based transmission fluid to a synthetic transmission fluid.  Synthetic fluids have much better properties than their organic cousins. The will not thicken up at ultra-cold temperatures, nor will they turn to varnish at higher temperatures. Using a synthetic fluid could really extend the lifespan of your 4L30-E transmission.

With the proper care your 4L30E transmission in your BMW 328i can serve you well for a very long time. Just like anything else, it needs the proper maintenance.  Be sure to get your transmission on a regular scheduled service plan. Although BMW recommend you can go a lot longer in between services, I recommend that you have your transmission serviced every 25000 miles, sooner if your doing a lot of hard road racing.  Here is to happy, and safe road racing with you 4L30E equipped BMW 328i!

Eventually, due to high mileage or abuse, you will be faced with a decision to replace the 4L30-E transmission in your BMW 328i. I highly recommend going with a re-manufactured transmission over one that was simply rebuilt. A re-manufactured transmission comes with a much better warranty; three years compared to an average 90 days for a rebuilt transmission. In the rare event that you need to contact the company that re-manufactures transmissions, they are just a quick phone call or email away!

Troubleshooting Problems With the Solenoids in Your Explorer’s A4LD Transmission

Posted by on Friday, January 24th, 2014

The A4LD is a four-speed overdrive automatic transmission built by the Ford Corporation. It is heavily based on the earlier three-speed C3 transmission, with basically an overdrive unit attached to the back end. It is a fairly light duty transmission, and therefore was only used behind weaker four and six cylinder engines. The A4LD was first put into production in 1985 and was eventually pulled out of use at the end of the 2002 model year. It was used in many different Ford vehicles, including the Bronco II, the Mustang, the Thunderbird, the Ranger, the Aerostar, along with the Mazda Navajo, the B-Series and the Scorpio. It was also used in the wildly successful first generation Ford Explorer.

Prepare The 5H24 Transmission In Your 840i BMW For Racing

Posted by on Wednesday, January 22nd, 2014

The 5HP24 is a five-speed automatic transmission made by the ZF Corporation. It is very similar in design to the 5HP24A. The 5HP24 was first used in 1996 and remains in production today. It was used in many popular makes and models, including the BMW 540i, the Jaguar Vanden Plas, the Ranger Rover, the Audi A8 and the Volkswagen Phaeton. It was also used in the very popular 840i.

The 840i is a very cool car. When it first came out it looked way ahead of its time. It even looked a little exotic. They were fast – very fast.  As the cars aged, they became more affordable to enthusiasts, especially those looking for an affordable car to go racing with. The 840i fit that bill perfectly.

Many BMW Clubs hold racing events around the country. Cars can reach speeds over 150 mph. Racing can be very hard on a car and all its systems, especially the automatic transmission. Let’s take a look at a couple of things you can do to protect the 5HP24 transmission in your BMW 840i.

The biggest issue you are going to have to deal with is excessive transmission temperatures. The 5HP24 is designed to operate at a maximum temperature of around 200 degrees. For every 20 degrees you go above that limit, you greatly risk cutting the life expectancy by a factor of two. You need to do everything you can to prevent exposing your transmission to overheating conditions.

5H24

The best way to rid your 5HP24 transmission of excessive heat is to install a performance aftermarket transmission cooler. Most transmission coolers are made to be a universal fit. They come in many different shapes and sizes. There are literally 100’s of different options available to you.

Ideally you want to choose the largest transmission cooler that will fit your 840i.  Be sure to mount it in a location that will see maximum airflow when the vehicle is in motion. For the maximum cooling benefit, mount cooler in cooler line exiting the factory cooler.

Another recommendation is to swap out your organic oil based transmission fluid for a synthetic fluid. Organic fluid will start to break down and turn to varnish at temperatures as low as 240 degrees. Synthetic fluid will not. Likewise, in extreme cold conditions, organic fluid will start to thicken up like honey. That is not the case for synthetic fluids.

Eventually, due to high mileage or abuse, you will be faced with a decision to replace the 5HP24 transmission in your BMW 840i. I highly recommend going with a re-manufactured transmission over one that was simply rebuilt. A re-manufactured transmission comes with a much better warranty; three years compared to an average 90 days for a rebuilt transmission. In the rare event that you need to contact the company that re-manufactures transmissions, they are just a quick phone call or email away!

Proper Care Is Key To The Longevity Of The U140F Transmission In Your Lexus RX300

Posted by on Tuesday, January 21st, 2014

The U140F is a four-speed automatic transmission that is designed and manufactured by Toyota.  It was first put into use in 1999 and remained in production through the end of the 2005 model year. The U140F comes from a family of transmissions that include the U140E, U142E, U151E and U151F. The U140F could be found in a variety of Toyota vehicles, including the Highlander, the RAV4 and the Matrix. It was also used in the popular Lexus RX 300.

Lexus RX300

The Lexus RX 300 is a small size SUV/CUV. It is popular with midsize families and often is used to carry precious cargo (your family). It is critical that you take care of the transmission in your RX 300 so that it doesn’t leave your family stranded in a dangerous spot, such as the middle of a busy freeway.

It is recommended that you get your U140F transmission on a regularly scheduled maintenance plan. Although Toyota and Lexus recommend that you can go more miles between services, I recommend that you get your transmission serviced every 30,000 miles. This is cheap insurance that will give your transmission the best chances of a long, useful lifespan.

U130F

Since transmission services vary from shop to shop, I have come up with a handy list you can use to assure that your transmission gets the proper care.  Here is what a true transmission service should include:

  •   Drain and replace the transmission fluid
  •   Flush the transmission cooler
  •   Flush the transmission cooler lines
  •   Replace the filter
  •   Clean any screens
  •   Check the torque specs on the valve body
  •   Check the resistance on all the electrical solenoids
  •   Check the operating transmission line pressure (in all gears)
  •   Scan the vehicle CPU for pending error codes
  •   Adjust bands as required
  •   Inspect and lubricate the shifter linkage
  •   Inspect rubber transmission mounts for dry rot and stress cracks

Another thing you can do to help prolong the life of your U140F transmission is to upgrade the transmission fluid. The U140F originally came from the factory with organic oil based fluid. I recommend you swap out your original type of fluid for a synthetic fluid. Synthetic fluids are much more stable. It will not thicken up in cold temperatures, nor will it break down as easily at hot temperatures, as its organic cousin.

Eventually, due to high mileage or abuse, you will be faced with a decision to replace the U140F transmission in your Lexus RX300. I highly recommend going with a re-manufactured transmission over one that was simply rebuilt. A re-manufactured transmission comes with a much better warranty; three years compared to an average 90 days for a rebuilt transmission. In the rare event that you need to contact the company that re-manufactures transmissions, they are just a quick phone call or email away!
