5R55E Slippage!

I got my first ranger about two months ago with 35K miles, and it now has 36.1K miles. My tranny slips in first gear. In a dead stop, I have to get the RPMs up to 1000 to 1200 before it engages. Sometimes it engages quite hard too.

Also, when I gas it hard (from a rolling start) it works fine, but when I let off the gas, the tranny has a problem finding gears. It may be in second, shift to third, then to fourth, then back to third, then back to fourth. All in about 2-3 seconds.

Is there anything I can do to fix this problem myself? My warranty expired and I don't have an extended warranty. Needless to say, I don't have the funding to take it to a tranny shop.

Hmm you might be ou tof luck, but you can try and take it to a dealer to see if they can fix it. If not you can take it to a transmission shop and have them put a shift kit in for you. Usually rusn about $500, but it will improve the shifting over stock, or so I have read.

sounds like it needs to be flushed out and have the filter changed, those are some common symptoms.

also, if you take it to a good dealer, there is a grace period in the warranty that some of them can take advantage of, if you go right away and still have just over 36,000 miles, and tell them it was doing it before it rolled over but you didnt have time to bring it in. they may help you out, ive seen it before

Is there any adjustments (such as band tightening) that I can do in addition to a fluid and filter change?

be prepared for a run around. unless your transmission grabs the technicion by the gonads, dont expect them to find anything.

have any of you guys done a real tranny flush and filter? these trannies start to act funny if they havent been serviced right, i do a tranny flush every 25k miles or so, its not too expensive, and way cheaper than a tranny down the road

mine has been done every 25k. im at 65k now. once i get to 75k, im getting a bigger tranny pan, shift kit, new valve body, and whatever else i can find for it. id really like a new torque converter.

my main issue is over use, and heat.

At 23k I drained the pan, changed the filter and all gaskets and rings, rtv'd it together, then filled it back up. I was thinking about doing a full flush but I need to get exact numbers before I start dumping a bunchs of quarts of (expensive) merconV into a 5 gallon bucket.

I was hoping that the pan fluid and filter would recharge it a bit and I don't think it did a damn thing.

You only changed the lube in the pan, which is about 4 quarts. The old lube is still in the torque converter...well was in the torque converter.

The total system holds 12 or 13 quarts I believe. Ford charges about $100 bucks to flush, clean, and re-fill the whole system.

All you have to do is disconnect the out line that goes to the transmission cooler.
put some plastic tubing over it with a pipe clamp.
put the tubing into a bucket.. get an assistant to start the engine..
and dump some quarts into the transmission as it pumps into the bucket
if you fall behind adding the atf you just shut off the engine until you catch up

do this for about 12-14 qts after you drop the pan and change the filter.
and you should theoretically change out upto 90%+ of your fluid.

Just be careful it can get messy if you jack up the process.. I ended up with
atf EVERYWHERE when the tubing kinked doh.

Ok today I had a large tranny cooler and a shift kit installed in my ranger, this included a flush and filter. The guy that did the work said he noticed the oil was alot darker/dirtier then it should have been (at 29600 miles) and he suggested that I change the oil every 12 - 15k miles.

If your oil has a slightly burnt smell to it then it should be changed, if it has a sweet berry smell to it then it should be fine.
