A razor blade, razor knife, or a small pocket-knife with a very sharp blade comes in handy here. An air ratchet and an impact gun speed up the rebuilding process considerably. You still need to help the seals get past the edges without damaging them. They still provide stability for the unit and the ability to lock it into any position, but the tool must be removed to install the oil pan and complete the rebuild. Impact guns can be used to remove stubborn fasteners such as those that attach the tail housing or rear transmission mount to the case. Nobody guarantees a rebuild when using an old converter.
They come with a tap, several threaded inserts, and a special tool to install them. Some metal on the nut at the end is usually raised up enough so that it does not pull through the case. Places like Harbor Freight offer inexpensive holding fixtures, designed for most transmission types, that work well for disassembly and assembly. Use wraparound goggles that keep debris well away from your eyes. A few minutes with a torch can quickly take a couple of small flat-blade screwdrivers and turn them into friction and steel removal toolsBy bending over the ends, they can be used to reach inside clutch drums or into the transmission case to pull steels and frictions out.
They also provide some protection against cuts from the jagged edges inside the cases. They can be used for a wide variety of techniques when repairing a transmission. You will also be using compressed air for drying parts as well as air pressure for testing clutch packs, servos, etc. Here are the 3 types of pan filters: brass ----- felt ----- nylon Here is your 350 'Tip of the day': While the transmission is out of the vehicle, inspect the flexplate. A Place To Work It is impossible to successfully rebuild an automatic transmission on your filthy garage floor or workbench, nor can you do it with an inadequate tool crib. Eye protection is a must anytime compressed air is used.
Workbench If a holding fixture of any type is to be used, it needs to be securely attached to a heavyduty table or workbench. Inconel or music wire works best because it is more rigid than soft metal wire. Several companies make threaded-insert kits. High-frequency noise from power equipment can damage hearing, which calls for earplugs or muffs. A suitable working surface is a must for building transmissions. Clutch frictions and steels must mate precisely and smoothly. Because no oil pan bolt holes are used, the entire transmission can be taken apart and reassembled while in the holding fixture.
Use a blowgun and compressed air to do a function test of the forward and direct clutch packs prior to installing them in the case. Engineered to withstand the rigors of daily use, Cuda Kärcher Group has been producing the highest quality in automatic aqueous parts washers since 1993. They allow the wrench to slip over the tube, and still get a good purchase on the flare nut to remove it easily. And, Phillips screwdrivers also double as alignment tools when putting the pump back on the case. For drums without a center hole, the component must be held stationary and some sort of spring compressor used to push down on the spring cage to facilitate the removal of the snap ring. It mounts easily in a large shop vise for clutch drums with a protruding shaft. A good bushing driver set is not inexpensive, and really not needed if you are only doing one or two units.
If the modulator is not plugged into proper vacumn, the trans will shift very late. It has served me well for decades and the total investment in the part was only a few dollars. Gently clamping the valve body in a shop vise with soft jaws or wooden blocks makes the job even easier. All parts must be kept dirt free and working smoothly for correct function. The other end of the dial indicator has a depth gauge, which is another handy tool. We welcome your comments and suggestions.
Special seal installation tools are available for all transmission models. This repair is stronger than the original material. For bushings that are driven in below flush, you can split an old bushing and use it in combination with a flat driver. Use a large punch ground at an angle as described above to remove this bushing. A complete and correct rebuild can be accomplished in a small shop or garage. The factory was kind enough to provide chamfered edges to help with seal installation. Angled correctly, it is like keeping a finger gently pushing against the converter, lightly holding it in.
A good respirator keeps all chemicals and particulates out of your lungs. A set of soft jaws can be added to hold shafts without damaging them. The more surface area on the top of the bench the better, as it allows you to keep the parts separated and organized during the procedure. Sliding valves must glide through the valve body smoothly. Also use a good pair of thick chemical-resistant gloves. Always use a respirator, no matter how well ventilated your shop or driveway is.
