For the last few months I have been having sort of sluggish performance and very notchy shifting, especially between gears 1-2 and 3-4. No grinding, no lockouts, nothing like that, just sort of a slight hesitation taking off and between shifts. I feel lately that the transmission has not been very smooth. After doing a lot of research and asking several members in this forum, a lot of people recommended changing out the OEM fluid for Amsoil Synchromesh. I purchased 2 quarts ($16 each) and replacement crush washers and took it to my mechanic who changed it out for $20, and damn, I am glad I did it!
My shifts are now buttery smooth, all gears, and the transmission is very smooth and responsive. I didn't feel and joltiness in any of the gears like before. The second and fourth gear notchiness is still there, but much less than before. I was so impressed by the performance increase and smoothness, as I was driving back to work after picking my the car from the mechanic I took a bit of a detour.
I would more than recommend to everyone who feels that they are experiencing transmission sluggishness and who have not changed out their MT fluid to get it done, and I would highly recommend Amsoil Synchromesh. Hopefully this fluid will keep the transmission smooth until my next change in 30K. We will see...
