I have an '86 Toyota pickup. I jut replaced the clutch 1,500 miles ago and now my truck is beein selective on when it wants to shift. At random times it doesn't want to go in gear and the only way it will is if I stomp the clutch and jam it into gear... And I'm pretty sure this damages it more but what else am I gonna do on the highway or in traffic? But also at other times it shifts so smooth it feels like a brand new civic. I just hve no idea what the problem is.

Please help!!! This is my DD.

 

R/R shifter seat and bushing.

 

Gonna order the marlin one's tonight thank you.

 

Where in the pedal travel does your clutch engage / disengage? If your clutch isn't disengaging completely, you will have trouble shifting. Since the problem is intermittent, you might have something like a release fork pivot problem, or your clutch master or slave cylinder is starting to go, and getting a little air in the line.

When I pulled my transmission recently, I found that the shift seat bushing wasn't even installed! No wonder the shifter had so much play! The idiot mechanic from the used car lot I bought it from was the last person to have the tranmission out. (He had to replace the clutch.) I drove the truck like that for thousands of miles, up until recently. It still shifted fine, I just had to shift it a little slower than normal, especially going into 4th. Other than that, it worked fine even without a bushing.

Please keep us posted on your findings. I'm curious to know what takes care of it.

 

I'm gonna take it apart tonight and look.

 

Also check to see if the bracket holding the clutch pedal is cracked.

 

have you checked your oil level?

 

Make sure you've got GL-4 in the tranny. If the more common and available GL-5 was put in, that could account for the hard shifting since GL-5 is too slippery and the synchros don't work. Plus, most of the GL-5s have sulphur which corrodes the brass synchros. Amsoil MTG & Red Line's MT-90 are the best.

 

I'm about to check right now.


Engine oil is full.


Haven't a clue of any of that.

 

hey let me know how it all goes i have the same issue with my 81 5 speed

 

I was talking about the transmission bud.

 

 

....yea totally knew that .


Heading back out to the truck...
And the bracket is fine lumpy.

 

Oil was real real low. Like a cm of fluid. Does the 22r take a special kind does anyone know? Or is all transmisson oil the same? I have no clue about transmissons.

 

Well if I recall I used 75-90 in mine, same in the t-case and the diffs. I used the Lucas gear oil and so far I've liked it.

I'm just reposting what someone else posted. When you look for the oil make sure it has the gl-4 rating on the bottle.

 

i believe sb5walker has already answered you "Make sure you've got GL-4 in the tranny.

I meant is all gl-4 oil the same. Brands people. That you lumpy.

 

Now this is for my own info...I know years are different. I have a 92 they say either GL-4 or GL-5 in my owners manual. Should I stick to 4 as well or is that just for the later models?

 

Whatever you do, DO NOT USE LUCAS GL-5 GEAR OIL in your manual tranny!!! Check out how badly it corrodes copper (which means it will also destroy brass which is mostly copper) on pages 16-17 of this study:
