I was told that the first gear in the TM70F 5MT transmission (FWD) is not synchronized. Is this true?  I thought this transmission was the same basic one as that in the push button 4wd cars (TM75F I believe) and I can definitely downshift into first while moving slowly without grinding.

 

Also, the Haynes manual states that the transmssion is "fully synchronized". I cannot find any definitive information regarding this so if anyone has that please speak up.

 

Thanks.

Hrmm, my 87GL has a TM70F FWD 5MT transmission and 1st is definitely synchronized. I would be very surprised if there was anything different internally vs a phase 1 EJ FWD 5MT.

 

With custom carrier bearings you should be able to fit an LSD ment for a AWD 5MT too. A friend did this in a p1 EJ FWD 5MT.

Regardless of synchronized or not I've always found it ideal to double clutch and Rev match in to 1st.

I'm with you there, double clutched and matched.. you can stuff it into first at 25-30mph. I would venture to say the same exact closing speed as my wrx if done correctly.

I emailed Subaru and here is their response:

 

Dear ----,

Thanks so much for your most recent email and I appreciate you providing me with
the VIN for your vehicle. It is also great to learn that you are still driving
this vehicle since August 1994!!

I did have the opportunity to review your question with one of our Technical
Representatives who explained to me that the transmission in your vehicle is
fully synchronized - first gear through fifth gear.

Once again, thanks for your email and I appreciate the opportunity to assist
you.

Sincerely,

Jody Cullen
