Just replaced my tranny fluid last night. The new pennzoil synchromesh replaced the redline oil thats been in there for 15k miles. Very noticible difference, shifts much smoother, the slight grinding i previously had was all gone!
Mitsubishi diaqueen lsd oil went into the transfercase and rear diff. They replaced the oil redline oil in the 2.

For ~$5/quart on the synchromesh, i was skeptical initially for it being better than redline. Changed my mind 5 mins after the oil change

 

good idea getting that redline out of the diff ant tc case

 

I agree.
GM/Penzoil Synchromesh for Tranny, and Mitsu Diaqueen LSD for TC and rear Diff.

 

i have the B&M short shifter and after replacing the tranny fluid with the synchromesh, the shifting is less effort compared to redline.

 

Where can you buy the GM/Penzoil Synchromesh for Tranny ?
Auto Zone, Pep Boys,K-Mart etc.
Is it for all types of transmissions or does Penzoil sell for other types also.

 

i got mine from autozone......not all of them have it, had to go around different ones to find it

 

Yup Autzone its like 4.98 or 4.89 in MD

Probably the way to go changing your trans fluid.

 

the only downfall to the pennzoil is that it only last about 5000 mi.. who cares its cheap and it works good.. me i run syncro. in the trans, and mobil syn, gl-5 in the rear and t/c.. no probs..

 

Got my synchromesh today. Auto Zone $21.00 for 4 quarts with tax.
Defarmer, Why do you say 5K life span on this oil ? Nothing is written anywhere
about this. Is it from personal experience ?

 

Can anyone else confirm the 5k life of synchromesh?

 

when is good mileage to replace your stock drivetrain fluids??? I have 9k on my car

 

It's a good idea to change all the fluids after break-in period.

 

^^^ACA i would go with 10- 12 k miles to change fluids

 

i'd like to know about the penzoil only last 5k miles too. also, to anyone that has already bought the synchromesh from a place like autozone, is there a part number of anything on the bottle to verify that i get the right one. thanks.
