UTI Automatic Transmission Drum Rebuild

Tuesday, September 27th, 2011

The modern automatic transmission is by far, the most complicated mechanical component in today’s automobile. Automatic transmissions contain mechanical systems, hydraulic systems, electrical systems and computer controls, all working together in perfect harmony which goes virtually unnoticed until there is a problem.

Trying to beat my record at tearing down and rebuilding a clutchpack assembly for a 41TE transmission….. my friend taping accidentally deleted his whole card with my best 33 second run on it!!!! I was trying to beat or meet that time again on this video but couldnt quite do it….. A new world record anyone suppose?

Honda Civic Transmission Output Shaft Seal Replacement

Tuesday, September 27th, 2011

This video shows how to replace a leaking transmission output shaft seal on a 1997 Honda Civic, but should also work for Civic manufactured during 1996-2000.

You will also learn how to replace a drive axle, because it is taken out when the seal is replaced. Remember you do not have to take the rubber boot off, it was easier for me to so I was able to get a good grip. Also, make sure when installing the seal it is flush with the transmission case, you do not want to force it and push it back too far or it will be ruined by other moving parts inside the transmission. I received estimates from 3 different transmission shops to do this transmission seal replacement ranging from $120-$170. The seal only cost $16, and it took my 1 hour to replace. Tools Needed: 17mm Socket 32mm Socket Seal Torque Wrench Screwdriver (flathead) Pliers Jack stand Car Used: 1997 Honda Civic EX Coupe 5 Speed Manual.

Servicing an Automatic Transmission

Thursday, September 22nd, 2011

The Fluid change in an automatic transmission in your vehicle promotes proper operation and helps your automatic transmission last longer without failure. All vehicle manufacturers have different service intervals for their particular transmission. In a typical automatic transmission service, the fluid is completely flushed, a filter is changed, the transmission pan is cleaned and a new pan gasket installed. When refilling, use manufacturer specified fluids.

Regularly check your parking space for leaks. Doesn’t matter, is it the engine oil leak, power steering fluid or transmission fluid; if you discover any, get it fixed before it caused something serious. Change the fluid as often as it said in your owner’s manual or when it becomes too dark (rather brown than red) or dirty.

How a Automatic Transmission is Made

Wednesday, September 21st, 2011

The remanufacturing process of a BOSS Transmission starts with the proper identification of the transmission. The used transmission core is then disassembled, washed thoroughly using biodegradable cleaning solutions, in an industrial, high-temperature transmission parts washing machine. Each internal part is inspected thoroughly for OEM specifications. All parts not meeting OEM specifications are discarded and replaced using a variety of quality new OEM and aftermarket parts, such as Honda, GM, Chrysler, and Ford OEM and other parts providers.

We use aftermarket new parts, such as Borg Warner, Transtec, Sonnax, Raybestos, Precision, and Rostra, just to name a few. Each transmission unit is carefully re-assembled and updated using the latest technical service specifications, such as, valve body re-programming, super-ceded parts replacement, bushing updates, electronic updates, torque converter bearing and lining updates, all of which are required to meet BOSS Transmissions building standards. Each of our transmissions are built by a knowledgeable and experienced transmission technician from start to finish, ensuring a quality tested rebuild remanufactured transmission. It is then ready for you to replace that old and non-working transmission with a quality tested rebuild or remanufactured BOSS Transmission.

4L60E Automatic Transmission Shift Kit

Saturday, September 17th, 2011

Before you rebuild your 4L60E Transmission you will need a rebuild kit. Most higher end rebuild kits will include a new shift kit as well. An automatic transmission shift kit is only needed if you want the gears to shift sooner, but it can also reduce transmission wear by reducing or eliminating shift overlap

Mercedes E270 CDI Automatic transmission Rebuild

Saturday, September 17th, 2011

Here is a Mercedes Benz E270 CDI that has a problem when the car is shifting into 2nd gear. Most likely the second gear clutch pack has an issue. Either one of the clutch discs in the pack or the pressure plates is blown. So I needed to get the transmission overhauled.

AOD Transmission Oil Pump and Piston Assembly

Tuesday, September 13th, 2011

The AOD (for automatic overdrive) is a four-speed automatic transmission with overdrive. Introduced in 1980, it was Ford’s first four-speed automatic overdrive transmission. The 4R70W stands for 4 gears, Rearwheeldrive, 70 stands for the 4th gear ratio, and Wide gear ratio. It has lower 1st and 2nd gear ratios for better take-off acceleration and improved gearset strength.

The AOD was used originally on ’80s and early-’90s Ford, Lincoln, and Mercury products and in the F-series pickups and E-series vans as well. Because the AOD is basically a retooled C-4, many classic car owners have discovered they can substitute this overdrive transmission into their ’60s and ’70s production vehicles relatively easily and reap the benefits of a lower final gear ratio and decreased wear and tear on their vintage small-block V-8 engine. Theres more parts to take off of this but I will do that when the rebuild kit gets here, just to make sure I get the right parts.
