I had my tranny swapped out and a rebuilt was installed about a week ago. I am having the same slipping problems I did before the swap. When you are at a stand still and apply the gas sometimes it just revs and then catches. It is very intermittent and had not done it for three days then just this evening did it four times. The second time just about killed me as I was not able to get out of the way of a truck. I am wondering if it could be the computer and If it is can I just purchase a used one and swap them out, is it that easy? What other ideas may you all have I am about at my witts end with this truck and I am about to scrap it. I have spent 1600.00 in the last two weeks with the tranny, new brakes ect that I don't have much money left to spend replaceing parts that are not the problem. The alternator was changed not even a year ago from the last owner

last night when i tried to drive out of my jobs parking lot...i reversed out of the spot, clicked it into drive, and began moving forward in first gear. After a small distance i continued pressing the gas and it revv'd pretty good while not moving at all. Then once it caught the truck went forward. Shortly after that i was at a stop sign and tried to move forward beleiving i had enough time to make it across the street. The truck revv'd really good but again did not move. Once it clicked in it shot me into the street a little bit .... in front of the truck ! Needless to say that is a safety issue.



This morning I took the truck into Mr.Transmission since they offered a free 21 point inspection. The owner was the one that I was dealing with all day and he is also a certified tranny mechanic. He said that he test drove the truck three times today and he did not feel any drag or slippage. Once again the truck proved me as a liar...lol. He said that they also put it on the hoist and hooked the computer up to see if there were any tranny codes past and present and he said that the computer came up with nothing. I told him that I didn't have any check engine light come on about the tranny even before it was changed. The only codes that came up were the onesyou helped me with for the EGR system. While up on the hoist he said that he did notice the tranny leaking from the front torque converter seal but that was it. I called the guy who put the tranny in for me and told him about the seal and he said that if I bring it back on Tuesday he will fix it he had no Idea that it was leaking. On the way home today after picking the truck up from the transmission shop it did not act up at all. One thing I noticed was if I take it out of OD the truck is not sluggish it has better pickup. I only drove a short distance out of the overdrive and it didn't act up. I told the mechanic that I know there is something wrong and I was affraid that I was going to wreck this tranny if I continued to drive it. He could not say much because he has nothing to work with at the moment. I asked him if it could be my catalatic converter because a friend had a similar issue and after taking it to two tranny stores they said that her tranny worked fine then took it next door to a muffle shop and they found herconverter was melted and causeing her problem. When I told him her storey he said that many people come in thinking that is the case it is very common but he told me that is not my problem. He told me how he knew but I can't remember exactly how he put it. Well I don't know what to do from here I don't want to pull my tent trailer if it is not functioning properly but how do I know it's not. The tranny was a swap out two diffrent trannys I could see it doing the same thing if we used the same one. in the last 2 weeks I have put about 1600.00 into this truck and when you helped me out I put in 500.00 when does a person stop. Do you have any ideas on what I can check that might be giving me this dead issue? Brian when he does the seal is is going to check the "bands" agian he said. I am not sure what he is talking about there. Is it possile there could be air in the system causeing this to happen? Any suggesti
