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.
 
No magic bullet for a worn out transmission. Other than that...might want to check the transmission mount if needing replacement.
 
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.

have you seen this?


 
Are you shipping it?
Removing it diy style?
I have about 20k miles on it with one fluid change
having it r&R at a shop and bringing it to another shop for a bench rebuild. I got a quote for labor and suspected parts from the second shop but am a bit worried it'll end up being more involved.
 
Depends on the trucks mileage. If it's a tranny with high mileage, expect the worst. Usually when high mileage parts are reused that appear so-so, you don't get the best rebuild. Something never seems right.

thanks 160K miles...don't know how the first owner drove.
 
Thats odd for needing one of these transmissions rebuilt at only 160k...usually its the ones well over 250k miles that begin going downhill. The previous owner must of shifted it a lot, having those issues already. Kind of makes one wonder how the clutch looks. I'd be willing to guess, there's not a whole lot wrong if driven normally.

I replaced the clutch a few years ago (the popping started recently). haven't put that many miles on it since. First owner had a full work shell on it and must have driven hard.

Learned long ago never buy a used work vehicle, especially a manual one that gets driven by more than one person. They usually get beat with poor maintenance. Idk if you can call that bad luck, more like bad choice.

yea he was an electrician...don't believe it was a crew truck. the 3.4, suspension, and most other parts has held up so far. fingers crossed. I might have to live with it for awhile if I can't find an affordable way to fix it.
