QU50457 AM 6 Bolt Round Transmission-to-Transfer Case Adapter Gasket

QU50457 Aftermarket 6 Bolt Round Transmission-to-Transfer Case Adapter Gasket for 1980-up Ford, GM, and Dodge trucks. This is a typical aftermarket gasket that does not meet original equipment specs for die cut dimensions, thickness or paper quality, however, for the low budget repair, it is far better to use one of these instead of assembling your case without gaskets!

Applications

Tech Note 1: RTV Sealant
There is no need to apply RTV to the gasket unless the mating flanges are gouged or damaged.

Tech Note 2: Dodge NP205
On Dodge NP205 applications, use of this gasket at the front of the factory adapter and an original equipment thickness hourglass gasket between the adapter and transfer case is critical for maintaining adequate clearance between the transmission output shaft and transfer case input shaft.

Tech Note 3: Dowel Hole
There are seven holes in this gasket. Six are for the mounting studs/bolts. The seventh hole is for a dowel pin which is mainly found on 1980-1997 Ford applications and a few Dodge models. If you would prefer a gasket without the dowel hole, order TK30052.

Tech Note 4: 1994-up
Effective with the 1994 model year, Dodge did not use any type of gasket between the transmission and transfer case, however if you wish to use a gasket for your 1994-up Dodge Ram, TK10519 is the part to use.

Tech Note 5: Lubricants, Sealants, Threadlockers
Early production NV4500 Transmissions used an anaerobic sealant (QU90003) to seal between the main case and input bearing retainer, top cover, and rear housing. Mid-production units used anaerobic sealant just on the input retainer and RTV for everything else. Later production transmissions used black RTV Sealant (QU90006 or QU90005) for everything. Either type of sealant works fine (except the PTO covers ALWAYS should be sealed with RTV), but I prefer RTV for all components. Regardless of which sealant you use, make sure excess sealant does not block the lube access hole at the top of input retainer pilot that fits into the transmission case. Also, the threaded holes in the main case for the four retainer bolts and 12 PTO bolts are open ended, so you must use new bolts with factory applied threadlocker or apply Threadlocker (S24200) to your existing bolts to prevent oil seepage past the bolt threads. See my TM1003 NV4500 Shop Manual or V1003DVD NV4500 Overhaul Video for more information.
