Transmission Seals : Transmission seals are on a transmission to seal moving parts. External transmission seals keep transmission fluid inside the transmission as well as the outside elements out of the transmission. Typical transmission seals include driveshaft, output, input, torque converter, and shifter shaft. Internal transmission seals help regulate specific sealing points inside the transmission. These seals seal shafts, drums, pistons, accumulators, valves, and other internal transmission parts.
Seals are made of rubberized materials or neoprene. Some seals are combined with metal or rubber coated metal to strengthen the seal. Other seals are as simple as a thin neoprene or rubber circular ring. An automatic transmission contains a lot of different kinds of internal and external seals.
External seal problems are easy to spot. This is because transmission fluid will leak out of the seal and onto the ground. Internal transmission seals are more difficult to see, since you have to disassemble a transmission just to see and inspect the internal transmission seals. Problems with internal seals cause noticeable transmission problems such as slippage, delayed engagement of drive or park, or no movement in drive or park.
Repairing external transmission seals do not require rebuilding the transmission, but in some cases a transmission may need to be removed or partially taken apart to replace these seals. Internal transmission seals will require a transmission rebuild and will be much more expensive than external seals.
