Redline MT-90 is the Bomb, and New Exhaust System Finished

[1SupraMk2]

Probably nothing new to most of you guys. I put a w58 in my 91 Cressida. Everything went fine except when I started it up it would not go into gear. I bled and rebled the system, it got better but would still grind trying to go into reverse.

I did a search and found that Redline tranny oils have worked out bugs in a lot of manual trannys. When I first swapped the w58 I drained the old oil and added common 80-90w GL-5, as the service manual said GL-4 or GL-5 was recommended. After researching it got me wondering if the GL-5 was not such a good idea and giving the syncronizers fits. I throughly drained the GL-5 and filled up with Redline MT-90. I'm kind of cheap and it hurts paying $15 a quart for anything.

When I started up the Cressie I could not detect any improvement, but I went for a drive anyway hoping the new lube had not worked its way over all the gears and syncronizers. Ten miles later I was all grins. Everything started shifting smoothly, and I could get it into reverse without grinding. Wow, $45 well spent. I'm a believer now and I'm going to put it in my Supra as well, although it shifts fine.

I have no doubt that Royal Purple and Amsol are great products as well, I'm not trying to reignite that debate. I'm just reporting on the amazing results I got with the Redline product.

On a side note, it was also the first time I got to try out the custom exhaust I fabricated for the Cressida. I wanted a free flowing system that sounded good, but I also wanted it quiet, it is my family car after all. I purchased mandrel bend 2.25" sections of pipe and went to town with my MIG welder. For sound control I had a barely used 14" Dynomax muffler and two new 12" glasspacks lying around. One glasspack went where the converter used to be, the turbo muffler replaced the forward muffler on the Cressida system, and the second glasspack replaced the huge muffler at the rear of the car. I took care to reweld the stock mounts to the new system. It took several days of hard work but I'm thrilled with the result. Its quiet but has a nice growl going through the gears.

Thanks for letting me share my happy moment today.

Redline FTW! I notice less vibration and smoother shifting when I switched over.
