Tuesday of last week I was driving home on the Garden State Cashcow doing about 70 and notice I was revving high for 70 just shy of 3000rpm'*, so I pulled off and started again counting the shifts. Well I only counted 2. NO OVERDRIVE!
So I took it into a transmission shop (have not gone to a second place yet) and they came up with 2 codes; one for the bad pressure selinoid and the other for too much clearance in the 2nd drum in the valve body which causes delayed shifts. But as far as im concerned I dont feel or notice any major problems other then the no overdrive, of course they couldnt trouble shoot that problem unless they take the trans apart to investigate for a modest fee. Im at 151,000 miles I just think its time for a rebuild of this one or I was considering purchasing a rebuilt trans and sending this one back as a core. The car is still very driveable so I have some time. Im trying to weigh in on whether I should purchase a rebuilt trans (which I know how much will be) or have this one taken apart at some chance that it doesnt need to be rebuilt. The problem with the 2nd option is if it needs to be rebuilt theres never a guarantee on the price. If anyone has some imput or would like to weigh in there 2 cents please do so.
