Hey my truck has a 351w and it shifts extremely hard while going only about 10-15 mph otherwise it shifts completely fine. it also seems like its shifting late, i know thats not very much detail at all but anyone having the same problem or can help?
Late hard shifts usually indicate the transmission may be in "limp mode". Try checking for codes before throwing money at the problem. If your truck has an E4OD transmission it is 100% electronic controlled. If you have an AOD you may need to adjust the TV cable.
If you have a transmission code "E" you have an E4OD. If it is Trans. Code "T" you have an AOD. Yes I realize the decoder says Trans. Code "T" is listed as 4 speed automatic for a Ranger, but my Ford Service Manual states that T is an AOD in F-series trucks.
