The present invention relates to automatic transmissions. In particular, the present invention relates to the GM 700r4 automatic transmission. More particularly, the invention relates to a novel bearing/oil seal designed to replace the OEM input to output oil seal in the GM 700r4 transmission which is known to have oil seal failure history. The OEM input and output shafts of transmissions produce substantial movement relative to each other. Excessive movement between the shafts causes rapid oil seal wear, oil loss, and transmission failures. The new bearing/oil seal design of the present invention serves to couple the shafts together, and provide a vertical sealing face for a more durable seal. The benefits from the new bearing/oil seal are less movement throughout the drive train, longer oil seal life, less binding of the ¾ clutch pack, longer transmission shelf life, and increasing overall durability.
A GM 700R4 automatic transmission comprising a highly durable bearing/oil seal design for coupling input shaft and output shaft to help control movement of both input shaft and output shaft and provide vertical oil seal so as to reduce the automatic transmission breakdown.
A GM 700R4 automatic transmission with reduced oil loss and breakdown comprising:
A method of modifying a GM 700R4 automatic transmission having an OEM input to output oil seal comprising:
