If you're faced with the decision on whether or not to fit your own torque converter and are unsure how to do this, then do not fret. We'll take you through how, in our step by step guide.
Depending on your speed and levels of skill, this job will take around three hours to complete. It is a fairly tricky job to undertake so please take the time to read through the instructions and ensure that you feel competent and confident in your ability to complete this work.
The first thing to note is that you will need to have the car jacked up completely, at both ends and of course ensure that it remains level. Jacking the car involves raising one side at a time and ensuring that both sides are jacked adequately.
The first step of the process to replace a torque converter is to locate the driveshaft. The rear axle will connect to this and at that location the driveshaft will be held in place by bolts- four in total. You will need to remove these bolts before continuing. The next steps will instruct you on what to do in order to remove the drive shaft from the rear axle.
Ensure that the van (or car) is in the neutral position. This is very important to enable you to turn the driveshaft. Carefully move the driveshaft so that it becomes loose, enabling you to free it up from the rear axle. Once you have moved the driveshaft, pull it away from the axle and once you feel you have done this enough, pull the driveshaft away at the other end too- from the transmission.
The next step in this process is to open the bonnet and locate the transmission filler tube. You will need to remove this tube and you can do this by following the tube all the way through to the transmission and loosing the bolt that holds it in place at this area. Once loosened, pull out the tube. It is important at this point that you ensure the car is back in park.
The next step in the process is to locate the torque converter attached to the transmission. You will need to go back underneath the vehicle for this. There are bolts holding these together which will need to be removed before you will be able to remove the converter. In order to remove the bolts effectively, you will need to jack up the transmission slowly. The reason for this is to take any pressure off the cross member, enabling you to disconnect the parts. Only once the pressure is taken off the cross member, should you try to remove the bolts holding these two parts together. The bolts connecting the cross member to the frame of the van or car should also be removed. Once this is complete, remove the cross member itself.
After this, disconnect the transmission from the engine and this is firstly done by freeing up the bolts connecting these two parts. You will most probably need a socket set for this. Once the bolts are gone, lower the transmission on to the jack and then on to the floor.
Next, pull the old torque converter from the input shaft. Congratulations- you're now ready to fit the new converter!
Firstly, top up the new part with transmission fluid in order for it to function correctly, and slide into place, into the input shaft. Gently push the converter side to side until it fits correctly, this may take a little manipulation to get it snug.
To secure the new parts, follow the sequence you took to remove the bolts in reverse order. You must make sure that everything is fitted correctly and connected together with bolts as was the condition found.
Once complete, you can now lower the vehicle ready for use. Check the transmission fluid and top up with some more new fluid if required.
Lastly, you will need to turn the engine on and let it run idle for a period of time- usually and few minutes in order that you can check levels when the engine is running and warm. If you need to top up again after this then so, it is perfectly normal for the vehicle to require another top up.
