So the next time you need to repair your Daewoo automatic transmission remember - all overhaul kits are not the same - you can never make a bad decision by choosing the best.

We suggest that you start with our professional troubleshooting and overhaul manual. This is the same manual you will find in deluxkit_large.jpgmost major transmission shops. These are model number specific and typically include 50 to 85 pages of detailed information, drawings, schematics and specifications. Detailed trouble code information that you can get from your vehicles on-board computer are explained, review of this data will give you a good idea as to the probable cause of the automatic transmission problem. Even if you don't do the work yourself the knowledge you gain may keep you from being ripped off at local transmission shop.

If you have particles in the pan of the transmission you can be sure that the same contamination can be found in the cooling system at the bottom of the radiator. With your overhaul parts you should also purchase two cans for radiator cooling system flush and completely purge out all contamination in the cool hoses both output and return as well as the radiator reservoir.

It is also recommended that you replace the torque converter, as it is difficulty to clean and purge out the contamination surely to be inside the torque converter.

This is an abbreviated list and other parts are available. If you need something that is not listed just let us know.

Maintenance Tips

Regular maintenance cycles and continued checking of fluid levels is critical to the life of your transmission. Operating temperature is the single most critical parameter effecting the life of the transmission. Keep the temperature down and fluid fresh helps the units typically last a very long time under normal driving conditions. We can supply a couple of aftermarket products to help you get the most out of your transmission:

Auxiliary Transmission Oil Cooler.

We can provide the Truco auxiliary transmission oil cooler for you vehicle it is an excellent auxiliary oil cooler that provide additional cooling capacity. The kit includes all parts required to mount the unit and connect to existing cooling lines. This is a typical do it yourself project. The unit typically mounts in front of the radiator. Your cost on this transmission life saving product varies by vehicle model and typically start at $54.94 plus shipping and handling.

Fluid Additive

Generally we don't recommend additives but we have found that the Lubegard "Automatic Transmission Protectant" at only $13.93 + S&H can:

  • Prevent overheating, reducing transmission temperature up to 40 degrees F.
  • Extend fluid life
  • Eliminates transmission fluid foaming and oxidation
  • Reduces wear throughout the transmission
  • Eliminates clutch chatter and torque converter shudder
  • Softens and modifies harsh shifts
  • Provides for smoother shifting
  • Eliminates objectionable noises during shifts
  • Keeps valves and governors free and frees stuck valves in valve bodies
  • Raises the thermal and oxidative stability
  • Only product that increases the fluids ability to transfer heat
  • Contains no Ash

Always consult and follow owners manual for maintenance intervals and requirements.

Overhaul Tips

Before you tear into the transmission, we suggest you first study the troubleshooting overhaul manual, add a bottle of our "Automatic Transmission Protectant" and put a few miles on the vehicle. This just might free valves and governors that are possible stuck in valve bodies. Be sure to get computer trouble code(s), see owners manual for technique to acquire malfunction codes. This will be a great assistance in diagnosing possible problems.

Twenty-One Steps to Successful Transmission Repair:

1) Do your research locate any technical bulletins pertaining to your transmission, ask your dealers parts department for bulletins.

2) Clean the entire transmission, including the valve body.

3) Check pump, valve body and case for warpage.

4) Flat file pumps, valve bodies, and cases. Just a few strokes with the file to knock off high spots and handling burrs.

5) Check all pump gear clearances.

6) Check planet pinion end play and side to side motion.

7) Soak all planet assemblies.

8) Soak all friction materials for 15 - 30 minutes.

9) Make sure all steels are in usable condition or replace. Do not sand or tumble steels when used against High Energy friction materials.

10) Inspect all surfaces upon which a band will ride.

11) Replace all rotating oil control rings.

12) Check all oil control rings and rubber products in the bores for proper fit.

13) Check all major support bushings and bushings that control lub oil.

14) Pre-lubricate all bushings and thrust washers.

15) Pre-lub pumps.

16) Pre-fill torque converter.

17) Use available manuals to ensure proper specifications and clearances.

18) Set correct clutch and band clearances.

19) Take the time to set the total end play.

20) Use a torque wrench on all pumps and valve bodies.

21) Always double flush the cooling and cooling return lines to the radiator to remove particles trapped there.

Take your time, take your time, take you time


Torque Converter Installation Preparation

Many torque converter problems can be avoided with proper preparation:

1) Pre-thread converter bolts by hand to make sure there is no sign of stripped threads.

2) Check and clean crankshaft thoroughly. Change crank spacer (if applicable).

3) Use 320 grit sandpaper or Emory cloth to remove any metal shavings on crankshaft.

4) Check converter for any damage that may have occurred during shipping.

5) Pre-fill converter with a minimum of (1) quart of transmission fluid.

6) Clean all paint off the pilot using 320 grit emory cloth.

7) Apply grease, not transmission gel, on the pilot.

8) Check flexplate for cracks and be sure there is no more than .006" run out.

9) Make sure all engine dowel pins are in place and clean.

10) Make sure all electrical ground straps are properly connected.

11) Never, Never us an impact gun to install torque converter bolts. Driving a bolt into the converter cover will create a dimple on the lockup apply surface. Lockup clutch failure will occur when the lockup piston applies against and uneven surface. Grinding off on thread length from all lockup converter bolts is recommended to avert this type of failure.
