Ford Transmission :: 1986 351w C6 Making Noise When Hot
Jun 7, 2013
I have a 1986 351w with a C6 sitting in my 55 F100. Its a project in progress, rebuilt 351 etc. Have not really driven the truck except for around the block a couple times, still work to be done however I do start it on a regular basis. Recently after the motor gets to operating temp around 190 or so the transmission start screaming, sounds like belts slipping or bearings. I first thought it was the water pump and replaced it last week, started it up today and same issue. No noticeable noise until she warms up, then sounds bad. How many miles on the tranny, over 100k I suspect. To rule out slipping belts and pulleys etc, I removed all the belts and same noise. I did notice after installing the trans and driving it around the block, that it shifts really hard into drive and reverse but the trans has not been used in probably 8 years or so. I've not drove the truck since it's started making this noise. I have the column out, but should have it back in tomorrow and may take it for a quick run around the block to see if noise gets worse.

I have a 3 spee Od out of a 1985 F-150 2wd . I was wanting to put it behind a Onan 6AT diesel . The engine came out of a P-350 bread truck . I runs great . I was wanting to know what the gear ratios are on the transmission . The engine has about 135 ftlbs of torque . The tranny was behind a 300 6 cyl . Iam trying to find out if this tranny will work or will I have to go to a N<!-- -->WC or TKO 5 speed .

I recently bought a 2001 x w 145,000 miles. The transmission was making a whining noise when i bought it but it still shifted smooth and ran great. The truck has been serviced by the local Ford dealer its entire life with dozens of routine maintenance performed. With 145,000 miles should I wait for the converter to go out and just install a new transmission. It only gets drove on the weekends to go to the lake.

My 1986 F150 in my signature has new 33" tires, up from the old 31" tires, and the even older 28" or whatever the stock size was. Needless to say, it feels pretty sluggish lately. First, I want to change the gears to get the engine back into a favorable RPM area while cruising. I used a calc and figured 4.10 gears would get me back to where it was with the 3.55 gears and stock tires.
There are several different spline counts and carriers and all that stuff. I need selecting replacement gears that will work, and first off, knowing if my carrier will even accept them. It has the stock Dana 44 front and 8.8 open rear...

I have a 1986 Ford Bronco straight six 300 4 speed manual NP 435
She grinded a bit when shifting from a stand still but nothing terrible for an old rig but leaked oil bad from the rear main seal so I took out the tranny/t case to put in new clutch, throw out bearing, pilot bearing, and rear main seal. When I put it all back together shifting into 1st would grind like CRAZY. So would reverse but not near as bad. So I took it all back apart inspected everything even torqued the clutch to specification. Put it back together and same result. So I replaced the slave/master cylinder thinking the clutch wasn't pushing enough bench bled it and still no luck.

I'm swapping a 90 E4OD into my 86 6.9 F350 and find my injector pump won't take the usual throttle sensor. I'm wondering whether the controller (from a 90 E350) cares about intermediate throttle settings or is it only worried about coast vs wide open.
My options appear to be rigging some sort of linear travel pot, or would limit switches with something cobbled together to give two resistances be enough?

I have just changed my transmission because the old one failed me and i notice that it makes a buzzing noise. It only makes this noise while in drive or reverse but when parked the noise goes away. My car runs perfectly normal but doesn't seem to "sound" as if it did. Its a 2000 lincoln ls. V8 4d sedan....

In Drive the engine revs but wont accelerate more than 25mph. D1, D2, and reverse work as usual. Fluid is dark, but no debris, no burnt smell. Should I change the fluid & filter? The shop said that would make it worse.

This is about a 2000 gmc sierrra 2500 truck I purchased with 194k a few years ago. It now has 232k. Whenever I go from a complete stop, the noise sounds as if it comes from the rear area. It sort of has a sliding umph noise, as if a slide hammer is going from front to back with a resounding stop as I move forward. I have checked the driveline, the rearend, the bed attaching bolts, and most everything in the rear section for tightness.
I had the bed loaded heavily once and it seemed to not make the noise. When I tow a boat or tow nothing it makes this noise with a sort of bang or stopping sensation at the end like the slide of something that then stops. Who wants to ride under my truck for a diagnosis? Could it be in the transmission? ha, it could be anything we all know that !

Rebuild on the Mazda 5 speed transmission. My 1986 Ranger 2.3 Four cylinder has 280,000 miles and the clutch has never been replaced. It's not slipping but I'm having trouble getting it into gear from neutral. Was told that the release springs on the clutch plate have weakened causing the clutch to not release completely so figured it's time to replace it. It's done well the last 280,000 miles. The question I have : overhauling on one of these Mazda trans and how difficult was it. Any special tools required, etc...I see Autozone has a rebuild kit which appears to have bearings, seals and gaskets. Figured while it was out I would go ahead and rebuild it myself if I can. Rebuilt a few engines but never touched a trans.

I have a '07 GS350 RWD with 121k miles. I had my transmission fluid drained and refilled at 90k miles.
Every time I go into reverse, there's a clunk noise. But all my gears shift smoothly.

New to the R, and recently the transmission seems to be making some noise throughout lower gears at low speeds, when the clutch is engaged the noise goes away, I figured it was the throwout bearing, but now my transmission now refuses to let me into 2nd gear and also reverse.
I changed the transmission fluid hoping it would eliminate the noise a bit, and saw very small metal shavings in the old fluid. I'm now worried I have a serious transmission issue... Are these signs of major transmission issues or should I be checking linkage? Any common transmission problems with the R I might be experiencing?

When you put trans in reverse makes whine noise no reverse. The forward gears are fine. Could this be a solenoid problem?

My grandma had purchased an almost brand new B6 Passat with the 4-motion VR6 all leather interior with about 8k on the odometer. Recently she has had some problems with it and has asked me what is going on, My dad has an Audi Allroad, my mom has a 01 A4 event and I have a 04 GLI so we know some stuff about the cars but these problems are eluding me and I was going to look for some counseling. First, her front tires are making this horrible sound, she says it sounds like a Mack truck and it gets worse as you go faster. I'm thinking its the tires but why would it be like that only after 8k? The second problem is her transmission, she has had the transmission fail to engage into gear 3 times, where it takes about 2-10 seconds before it engages. Now the car has about 10k on it. [URL]....

No codes, transmission makes a slight grinding noise when putting it into reverse only. Has a slight bump from 1st to 2nd. I flushed 16 quarts of the sp3 through it. Been researching and see a lot of talk about the output and input sensors. Not my car but my sisters. Needs axles, timing belt water pump, ps return hose, plus have champions in there and old ass hyundai wires.... thing does idle rough, motor mounts are new.
