Manual transmission hard to shift.

I have a 94 pickup. 2wd 5speed, extra cab. It is hard to shift the transmission from 1st to 2nd gear and into 3rd. You really notice it in cold weather (30degrees or lower). I have put synthetic gear oil in the tranni. Its better but still does it. When the tranni is warm it shifts better but never without feeling like its hitting the edge of the gear.

Also, if you're using a high-weight gear oil, I'd switch to GL-4 ONLY Redline 75 weight.

Since you don't mention grinding reverse, I assume no problems there?

Shifter bushings are likely. So is a generally worn transmission (synchros worn)

^^^x2^^^

Using synthethic or GL-5 gear oil can compound transmission shifting issues. These oils are slicker and don't allow the syncros to work as well as they can.

Toyota calls for 75w90 and if you use 80w90 or heavier oil that will also cause hard shifting issues most noticeable when cold.


Another cause for this kind of complaint is a clutch that does not release properly. a warped clutch disc or sometimes a master cylinder will bypass slightly causing the clutch to drag just a bit. This also usually causes grinding when trying to shift into reverse and can be worse when cold.

Hope this helps

x3 on the GL4. Switching to it fixed the hard shifting issues on my truck. Either Red Line MT-90 or Amsoil MTG



http://www.amsoil.com/storefront/mtg.aspx
http://www.redlineoil.com/product.aspx?pid=46&pcid=7
http://www.summitracing.com/search/?...%20mt-90&dds=1

The Amsoil product is a PAO-based Group IV synthetic, and the Red Line is an ester-based Group V. Although I've been using the Red Line with excellent results, shifting-wise, I've learned that esters tend to absorb moisture, which can shorten the life of the oil and can lower its pH. So since I don't change my gear oil too often, I think I'll switch to the Amsoil when I next change it.

BTW, GL-5 oil must be used in the differentials. Amsoil's Severe Gear 75W-90 is the best on the market; Valvoline Synpower 75W-90 is excellent too.

See this post for data on cold weather performance of a couple different oils: http://www.toyotanation.com/forum/sh...63#post3036163

Up until a few months ago, I had never realized that the GL4 is actually more appropriate for the Toyota transmission than the GL5. I read it on yotatec forum, before I knew that this forum existed. Since I've had the truck since new, I've always used the GL5 from amsoil, and I actually changed it several times over the last 15 years.... still having a tight shift stiff shift issue. I've already changed the shifter seats (bushings), and although it made it shift much nicer, it's still a little tough in cold weather.


Last week, I ordered the GL4 from Amsoil, and have since put it into the trans and transfer case (tonight, actually). I'm looking forward to seeing if or what difference it makes in the way the truck shifts, when I drive the truck tomorrow.

Since I have about 168,000 miles on the truck, I don't know if it will do any good, at this point, but I figured I'd give it a try.

Ok... Several days early...

But, I'd like to state the obvious... as my dermatologist always does...

"I have an opinion, but I reserve the right to change it at any time in the future, should circumstances correct my perception, or factual data is altered."


Well, day one with the "correct" fluid in the trans. Cold morning, and it didn't like to shift as what I would consider "normal" for the truck. It had a little more "solid" feel to it, but it still doesn't really like to shift from 1st to second, when it's cold...... As it's always been since day one.

Once the truck warmed up, the shift was noticeably improved.... although not enough to write home to mom about. Even though you could "feel the difference", it still takes some finessing of the "timing" of shift, as it's always been.

Here's what works in my truck.

First to second:

Shift @ either ~2750 RPM or 11-12 MPH

Second to third

Shift @ ~2750 RPM or 24-25 MPH

Third to fourth

Shift @ ~2750 RPM or 34-35 MPH

fourth to fifth...

It doesn't matter what RPM or MPH, as it goes into 5th easily.


These numbers are where it moves freely into the next gear (including from first to second), without binding or grinding or any other resistance.


Your mileage may vary.....

I tried the bushings and it's better shifting but not 100%. funny you mentioned about reverse. The only way I can get into reverse is if I'm at complete stop. If the truck is even slightly rolling it won't go into gear or grinds when you try to. Any suggestions keep them coming. Thanks!

That's how everyones reverse gear works. There are naturally NO synchros in reverse so you are correct that you must first come to a complete stop before shifting into reverse.

My suggestion is come to a complete stop before shifting into reverse. Your tranny will thank you!
