The transmission fluid is cooled by the radiator and will break down if run hot. This causes damage to the transmission. Changing the oil and filter would be a very good idea.

Can an overheating transmission affect the computer box? iam thinking that maybe the computer could have been affected after the transmission overheated

If you tranny is sending an error signal to computer it can prevent car from starting. Kinda like when you have the auto stick to choose Drive, Reverse, etc in the Reverse position car win't start unless in Drive. Take to a place that can read the code from the computer and it'll likely have an answer to your non-start. Hopefully you won't be spending $2000 for a transmission job!
Why change fuel pump? Was there no pressure on fuel rail? Was it not making its pump sound when key in acces. position? Did you check fuel filter if it indeed is a fuel related issue? Clues are awaiting your inspection such as rusted fuel tank, water in line, etc. by checking. But I'd want to know WHY you chose to replace pump since it has nothing to do with tranny.
IF a transmission related issue and you haven't gotten it to a place to read computer you might want to check if your vehicle has a separate transmission cooler up with radiator (usu. in front of radiator behind grill). See if fluid is flowing thru the cooler. If it is plugged then the transmission can have fluid but its overheated because its in a closed loop essentially and if it hasn't warped your metal trans. parts the overheated trans. fluid might send a stop signal to computer so won't start. Open T-valve and see if trans.fluid is in trans. cooler (again IF your vehicle has one, not all do but things meant to tow usu. do) and if so examine fluid and connections.

Where is the transmission filter located on a 2001ford escape, and how often should the fluid be changed? I have a problem somewhere because the fluid is a light brown in color. I had to replace the...

The filter is in the transmission pan. Fluid should be changed every 30,000-50,000 miles, depending on how the truck is driven. I would say yours is ready to be changed. Special equipment is needed to get all of the old fluid out, so take it to a tranny shop.

My transmission fluid turned brown. I beleive from getting hot.The bad radiator I think caused this. Should I change the fluid or leave it alone?

You are right to look at the tranny fluid as it has turned brown. This happens naturally over time and mileage. Depending on the mileage, sometimes it is not recommended to open the transmission pan to change fluid and filter. If over 100,000 miles, check with your local shop for tranny flush or fluid filter change per warranty consideration. You can add a bottle of Lucas Oil Transmission Stabilizer to your tranny without having to drain any fluids. I have used this often on higher mileage cars with great success. The bottle costs about $11. even at your local Walmart:) Read the instructions carefully as the full bottle contents need to be added with engine running and tranny warm. Hope this helps.

The only way that tranny fluid could get into the radiator is through the transmission cooler, which is inside the radiator. Maybe the replacement rad is NFG. In any case, the torque converter holds a lot of fluid, so just draining the tranny oil pan isn't enough. The torque converter needs draining as well to get all the bad stuff out. You probably just didn't get all of the old fluid out of it. Good luck with that.

2000 S80 Tranny wont shift to overdrive, and after stopping at a stop sign it wont shift to first, stays in 2 or 3, Turn key off and start the car, tranny shifts starts out in first, still no overdrive....

Greetings Idpeters:
Please check your transmission fluid level. After the engine is warm pull the transmission stick and make sure the level is close to the full line and that the transmission fluid is red and not brown. You may have to change your transmission fluid and screen. If you plan to do it yourself I can advise you on how to change it step by step or you can take it to a transmission shop or dealership for a transmission tune-up. Good Luck

My 1997 f-150 truck transmission started to give me problems

It's a tranny problem the anti-freeze in the coolant destroyed the clutches in the tranny and all of the seals. This is a very bad problem the clutch material and the seals in that tranny are not made to stand up to the anti-freeze. The converter is less affected by because it not in the sealed housing of the tranny.

1999 plymouth voyager water in trani fluid

your radiator has another little radiator inside the main radiator this is called transmission cooler seems to be than the cooler has a hole or is broken the main reason for this to happend is becasue the antifreeze or coolant is not been serviced at least every 50k miles or when you mix wo diferent coolants like diferent colors they get contaminated and create acids and start corrosion in the coolant system have the radiator replaced and flush the cooling system wiht lost of water then add only the designated antifreeze on greeen coolant 50/50 mix they sell it allready mix but if you but the one is not mix mix it with 50/50 coolant and destilated water but i recomend to buy 50/50/ green coolant
