I have a 1993 F150 SC SB 302 with the Mazda 5 speed. Today on my way to work the shifter got stuck in 3rd. I had the clutch to the floor and I couldn't pull it out no matter how hard I pulled. I pulled into a parking lot and had the clutch in and it finally slid out of gear. Any ideas as to what might be wrong? This is the first time it has happened. Did it come out because I had slowed to 5mph or so? Any info would be great.

Thanks in advance.
Anthony

You say that you got it out of 3rd gear, so is it working fine now? If so you just may need to service it. Or maybe its just low on trans fluid.

 

Boss_358 yes I got it out of 3rd when I pulled into the parking lot. I did nothing different though it just seemed to come out of gear. It drives fine now with no problems. I guess I will change the fluids and see if that helps. Kind of a stupid question but what do I need to use to change the fluids?

Thanks again
Anthony

The trans. takes 7.6 pints of Dexron II automatic trans. fluid. I don't think they sell Dexron II anymore so you can use Dexron III.

Make sure the truck is on a level surface. Drain the old fluid.

Purchase a hand pump at the auto part store. (The pump can also be used to fill the differential fluid). The cheap pump is like the pump in a Windex bottle but instead of a spray head on the output it has a plastic tube. It screws onto the Dexron bottle and has a tube on the end of it that you stick into the fill hole. You manually pump fluid from the Dexron bottle into the trans. until it over flows out of the fill plug.

There are also more expensive pumps that are like a syringe. You draw the trans. fluid into a cylinder and then insert the outlet tube into the trans. and push the fluid out.

If you discover you were low on trans. fluid and you notice a film of fluid in the trans. tunnel you may have a leak at
the three rubber plugs on the back of the shifter cover.

Over time the rubber plugs shrink and the trans. fluid leaks out. The solution is to remove the rubber plugs and replace them with brass plugs.

 

Well Thanks for the info F150xlt. On the way home from work yesterday it got stuck in 3rd again but this time I cannot get it out for the life of me. I managed to roll into a parking lot and turned the engine off to see if I could get it to shift out of gear with the motor off and the flywheel stopped. NO Luck. My brother in law is a mechanic and stopped by and we couldn't get the thing out of 3rd. Looking at it we think the problem is probably internal but he was saying where the actual shifter connects to the transmission there is a bolt going through the shifter. He said that on the passenger side there was a nut but on the driver side of the shifter there was no nut. Is that normal? Anyways I will take some pictures and post them today but it sounds like we get to pull down the transmission to find the problem. If anyone has any info it would be appreciated. Thanks again.

Also where would I find a rebuild kit for this transmission? I have searched google and haven't come up with anything for the Mazda tranny. Thanks again.

I'm no expert on this transmission, but I just happen to have mine a part and I'm replacing all of the bearings.

The missing nut for the bolt is to clamp the shifter lever to the stub which activates the forks inside the trans. via sliding rods.

If the shifter lever is still tight to the stub I'd say the missing nut is not the problem.

With that nut and bolt off, you should be able to pull the shifter lever off of the stub if it's loose.

Note: Below that bolt and nut you'll see a round metal plate with 3 torx bolts. If you remove those 3 torx bolts, the lever and the stub will lift straight off.

If you had the shifter cover off you'd see inside the trans. there are 2 shifter forks on the cover.

One fork is common for 1st and 2nd gear. The other fork is for 3rd and 4th gear. The fork for 5th gear and reverse is hidden inside the trans.


If you purchase any parts you have the late model Mazda
M5R2 used on a Pickup truck.

The Cougar and Tbird also used the M5R2 but it is a little
bit different from the trucks.

The early model truck M5R2's I think from 88-90 had a different number of teeth for the reverse and 5 gear syncro parts.

Here's a diagram click on this.

http://www.drivetrain.com/transillm5r1_m5r2.html

They don't give the part ID but item 16 is 3rd gear and item 14 is the sleeve that the shifter fork rides in for 3 and 4 gear engagement.

As for parts if you search on google for m5r2 it should bring up some dealers. Shop around because prices do vary.

I just purchased from one of the sponsers on this board Jeff's Bronco Junkyard a Bearing kit and it cost $160.00. A bearing kit with syncros cost $210.00.

I was able to jury rig tools to get the trans. tore down so I didn't have to use any of the Ford Rotunda specialty tools.

I had to purchase a large cresent wrench that could open up to 2.25 inches to get the output shaft lock nut off.

The toughest part was pulling the rear output shaft bearing.
I ended up using a brake drum puller.

Once the input, output and counter shaft are out you can use a bearing seperator tool and press to break the individual parts down.

I purchased from Harbor Freight Tools a 12 ton press on sale for $110.00 and a 4.25 inch bearing seperator plate for $12.00. The sale ends on the 27th.

I called around and the going local rate for bench work on the trans. is $600 labor plus parts. No way was I going to pay that amount. There are dealers on E-bay that sell a rebuilt trans. for $625 but you have to pay for shipping for your core.

If you live in the Baltimore, MD area I sure be interested in seeing what's wrong.

 

F150xlt thanks for your help. The shifter is still attached fine so I doubt it is the nut either. When I was searching online I did see the M5R2 transmission info but did not realize that was the tranny I had. I will hopefully get the whole thing down today and start looking for the problem. Unfortunately I live in Utah so I will have to just post pictures of what is wrong but i will definintely do so. I'll let you know any progress and thanks again for you help.

Anthony

P.S. Unfortunately my brother in law is a bow tie fanatic and just keeps saying "those stupid fords" and I have to get after him. Atleast he is a help when it comes to actually working on things.

Hey don't bad mouth your relative.

I also own a 89 and 90 Corvette. My 88 F150 (I'm the original owner) has 320,000 miles on it. Its been very reliable. I've gone thru/replaced 2 M5r2 transmissions so I figure I need to learn how to rebuild one.

 

I don't bad mouth my brother in law I just set him straight that Fords aren't bad and that it is a good truck. I don't have a problem with Chevy, his truck is pretty nice (at least the motor). He has a 400 ci and it is a strong motor and he can burn his 35's. Anyways thanks for the info and I will post my results.
