does redline manual fluid or any additive improve shifting?

I got a 99 popping out of first occasionally (after improvements of seat bushing and fluid change-used to pop out of 2cd and reverse occasionally). Really don;t want to replace transmission but got a behind the wheel drive test coming up in april.
 
Thx for the reply. The transmission guy (who only does bench rebuilds) told me this unit (R150) often has a worn linkage plate which is in addition to the rebuild kit. Then also possibly a new shift fork. Does this sound about right?

Yeah, anything that has to due with the internal linkage is suspect to, like played out detents, and interlocks. I've seen a bent shift fork cause hard to change gears in a manual transmission. Even seen worn synchros, and gears cause rough shifting issues. Rebuilding an r150 isn't cheap. If it's that worn out, the rest of the trucks drivetrain can't be far behind. I've been talking with a friend that his kid is going through similar issues with a worn out manual transmission in his 2003 tacoma. Seems gen1 guys don't know when they've had enough pain. Imo, it would be time to move on.

Thanks for the reply. one thing I wonder if the trans pretty much needs to be broken down to determine extent of the damage. So it would be left disassembled while having paid for the work already done if too much damage. I know that gen1 gets a lot of don't throw good money after bad.
 
If one can't see any obvious transmission issues once the tranny is on the bench, it's going to need tearing down for further inspection. I would expect any shop to charge their going rate for the teardown, and give you an estimate what they found. I'm glad you realize what you're getting intro. Transmission rebuilt, or not, be prepared to pay for the time the shop already has into it.
