Addicted To Boost Posted October 14, 2010 Report Share Posted October 14, 2010 I need to buy some MTF for my Getrag 282... I've done some reading on the net and found that there are (or were) 2 different versions of GM Synchromesh... just regular Synchromesh and also a friction modified version of it as well. Part number for the Friction Modified stuff is: 12377916 Can anyone verify the friction modified fluid is still out there? Anyone here have any personal experience with the fluid or recommendations? Thanks in advance Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted October 14, 2010 Report Share Posted October 14, 2010 12345349 is the p/n i pulled through alldata... SF grade 5W-30 was also recommended though.... Quote Link to comment Share on other sites More sharing options...
AL Posted October 14, 2010 Report Share Posted October 14, 2010 There 23 bucks a bottle from gm... The 91 when I had it leaked fluid from the axle seals so I had to keep adding synchromesh and they are 7 dollars a quart at any parts store but its penzoil which I read is an equivalent to the gm stuff... Buck hasn't had any trouble with the trans as far as I know Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted October 14, 2010 Author Report Share Posted October 14, 2010 SF grade 5W-30 was also recommended though.... Is that just motor oil? I only ask because I'm not really sure if mine is leaking... (probably is) because I checked the level today and there wasn't any oil on the dipstick Al, which one is $23/bottle? I've read that the regular GM Synchromesh is only like $8 a bottle, not sure how much the friction modified version is... Quote Link to comment Share on other sites More sharing options...
AL Posted October 14, 2010 Report Share Posted October 14, 2010 If you can find gm synchromesh for 8 bucks a bottle that's impressive... I talked to them directly at the dealer and they told me 23... I found the pennzoil at advance auto for 7 bucks a bottle... I haven't heard about the friction modified version honestly Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted October 14, 2010 Report Share Posted October 14, 2010 5W-30, yeah it's motor oil, just an old spec, SF, compared to the SM we use today. not sure if it is a good idea or not, but alldata suggests it for a 282..... maybe as a last resort?

Addicted To Boost Posted October 14, 2010 Author Report Share Posted October 14, 2010 On GMPD, the FM stuff is $8/bottle and the regular Synchromesh is $10/bottle.... shipping is outrageous though. I wasn't able to find any Pennzoil Synchromesh locally at O'reilly's or Napa. Quote Link to comment Share on other sites More sharing options...
WhatTheFehl Posted October 14, 2010 Report Share Posted October 14, 2010 I know we carry AC Delco Syncromesh at work... can't remember the price right now though. Quote Link to comment Share on other sites More sharing options...

White93z34 Posted October 14, 2010 Report Share Posted October 14, 2010 I run the penzoil syncromesh myself, its affordable enough and works good. Quote Link to comment Share on other sites More sharing options...

Mach 5 Posted October 15, 2010 Report Share Posted October 15, 2010 Doesn't the GM synchromesh have an additive in it that the Penzoil stuff doesn't? I believe its a semi- synthetic and penzoil is based off of the GM synchromesh but isn't the same. If the factory designed it for that trans then I would stick that in. I got my for $13 a quart its about $17 everywhere else Ive seen as high as $19 but I also worked at a dealer. Quote Link to comment Share on other sites More sharing options...
gpchris Posted October 15, 2010 Report Share Posted October 15, 2010 I've been running penz synchromesh from az. After my rebuild I'm thinking about running gm brand just to be on the safe side. I mean it's not likeyou have to refill or change it often + any dealer should stock it. Quote Link to comment Share on other sites More sharing options...
