Long story short I'm out of work and to keep myself busy and try to make a couple bucks i made up a few shifter gasket sets. The 3/16th thick Silicone rubber i use have excellent heat resistance (up to 425 F). Are oil resistant and these gaskets are twice as thick as whats available and twice as durable.These will fit the T5 T45 & TR3650 Transmission. The gaskets are hand cut by me off of my template.So the gaskets don't have a super sleek machine cut edge but my price also reflects that. If you are a Function over Form kinda guy then you probably won't care. PRICE IS $8.50 SHIPPED First Class Mail If you do decide to purchase this gasket set, keep in mind when your ready to install.The Shifter base as well as the transmission mounting surface must be cleaned of all debris or oil and to be dry. If the surface is not 100% clean the gasket could squirm or move around when you tighten the shifter.When your bolting the Shifter down its best to use a X Pattern putting a few turns on each bolt/corner at a time in a continuous X Pattern. Also If the holes in the gasket don't line up at first glance, Either flip the gasket over or turn it in the opposite direction to align as the holes only line up 1 way.The holes in the gasket are also Slightly larger (1/6) then the actual bolt holes in your shifter, so it should help give a tiny bit of wiggle room for alignment.
