GM Synchromesh in a T5

[jeffdg]

My search for T5 and trannyfluid seems that most use Dexron whatever, but have found a couple that use GM synchromesh in their T5s.

Having just rebuilt my T5 - are any of you guys using the GM Synchromesh? Why or why not? Are there benefits to this $10/quart fluid?

I just ran dexron in my T-5..Using Synchromesh in my 3550..

Synchromesh is what tremec says to use in their transmissions. I used just normal dextron oil in mine also.

Why not go synthetic? I just love Red Line products!

Use regular Dextron ATF fluid....do not put syncromesh in the T-5 the clutches are not made for it.

The synthetics are nice but they tend to not let the tranny go into gear in high rpms, we have seen this a few times.

Rick - what you mean by 'clutches' specifically? Are you talking about the clutching teeth on the gears and sliders?

Sorry, I ment the friction material on the syncros....

T5's should have at least Dexron.

My Jeep T5 was filled with plain old 90 wt gear oil when I got it. A very experienced local Jeep specialty shop said it would work fine as long as it was hot out, (he is in south Georgia) but to change it when I otherwise normally would.

It worked just fine for 3 years, I had to change the 3-4 synchro, and I refilled it with Dexron. Still worked fine.

I think the Dexron works in all of them. I know there are both brass and paper material faced synchros. I would not use gear oil in the paper type units. Dexron works in all of them. The newer fluids should be even better.

I used the GM Synchromesh.... I put it in my T5 in my 95.... much better.... very good stuff.... tranny shifts much smoother now...
