$10.00 Experiment

From my last MTF change I had 1 full qt of Castrol Syntorq 75w85 left. Since it takes 2 minutes to change the mtf on my KIa I purchased a drain plug crush washer and 1 Qt of Pennzoil Synchromesh.

I have about 400 miles on this mixture and it feels great. The synchro action between shifts is awesome, there is no delay like before when quick shifting at a high RPM, and it does not whine anymore slowing down to a stop at intersections.

I think I am going to go with redline MTL just to have all of the same fluid in trans.

Your post is confusing with information missing and a clear timeline.

Did you have some Redline MTL in there before and how much?

Did you drain what in there and mix the Syntorq and Pennzoil Synchromesh?

Assuming you used the correct gear oil, I would not expect much of a difference between gear oils. Especially once it warms up from usage.

I'd go with Amsoil SVG.

I had 1 qt of syntorq left over from my prior change and purchased 1 qt of synchromesh.

I mixed the 2 and it feels great

I am going to go for Redline MTL because its on the heavier side of the synchromesh derivatives. I just have to wait a couple weeks because I am closing on a house right now.

SVG is NOT a MT transmission fluid.

The fluid you have in there now has about a 10cSt viscosity so the MTL70W80 (a 10 cSt) fluid shoud work fine.

Here is a list of GL-4 rated Synchromesh fluids:

Quote:

C. The next higher viscosity MTL would be Castrol Syntrans V FE 75W-80 8.0cSt

D. The next higher viscosity MTL would be BG Synchroshift II 8.2 cSt

E. The next higher viscosity is Mopar Type MS-9417 MTL 9.0cSt

F. The next higher viscosity MTL would be Pennzoil Synchromesh 9.3 cSt



G. The next group of MTL’s are in the 10.x cSt range are:

1. Redline MTL 70W80.

2. Amsoil MTL

3. GM Synchromeshs’

4. Volvo MTF 645

5. Ford Motor Craft XT-M5-QS
