Like the title says, I have about 15600 miles on the car, changed out tranny fluid with RP max gear 75w-90 and now second gear is really hard to get into, sometimes i almost gotta force it in. All gears are actually little harder to get into but not to noticable, second is the worst. Car had OEM fluid in there before. I read that people use the syncromesh RP but haven't heard much about the regular stuff. Any ideas? Maybe just weight of oil?

 

i us redline mt90

 

I use what it was recommended by Redline. A mixture of MTL and MT90.

I heard that BG Synchroshift should be pretty good as well. Change that oil as soon as you can.

Just my 0.02!

 

its thick, the crappy thin oils shift great but offer little protection...

 

I've used Redline MT90 on all of my cars and never had any shifting problem. I will change the tranny fluid on my IX as soon as I put 3k miles on it. Right now I am still enjoying it on it's stock form.

 

so am i the only one that's used the RP max gear or what?

 

so you guys using that redline mt90, are you running it straight through or mixing.. i dont really like to mix stuff together.... to much of a pain.

 

You're the first i've heard using it

 

no i dont mix nutin.and stay away from royal purple......

 

you should really keep oem fluids if you want the shifter to feel like it did when you first got the car.

 

If you do some searching people have had a lot of problems with different types of fluids not offering protection. I would say stay with OEM fluids.

 

After reading almost every thread regarding poor shifting or difficulty getting in and out of gear i found that most people run either OEM fluids, BG Synchroshift or Pennzoil Synchromesh. There are others who have gone with Redline or Motul and been fine but the majority run those three.

I personally like the OEM feel the best and have had a few slight problems with the synchromesh.

 

i had problems with synchromesh.

 

i have royal purple now and its hard to get it in gear.... i think im going to go back to oem...

 

i se oem diaqueen its the best so far 75w-85 cause i tried bgII but after so much racing when i changed the oil out it had a little metal kind of teeth silver color i must of been on a misshift so i think bgII offers little protection i also used motul 75w-90 and gears where hard to put in so i stayed with diaqueen for me it works at its best.
search on bgII several members had there trannys fail due to using this fluid warrtalon was one of them i think.
stay oem fluids
